JWR’s Specific Recommendations For Developing Your Lists:

Water List
House downspout conversion sheet metal work and barrels. (BTW, this is another good reason to upgrade your retreat to a fireproof metal roof.)
Drawing water from open sources. Buy extra containers. Don’t buy big barrels, since five gallon food grade buckets are the largest size that most people can handle without back strain.
For transporting water if and when gas is too precious to waste, buy a couple of heavy duty two wheel garden carts--convert the wheels to foam filled "no flats" tires. (BTW, you will find lots of other uses for those carts around your retreat, such as hauling hay, firewood, manure, fertilizer, et cetera.)
Treating water. Buy plain Clorox hypochlorite bleach. A little goes a long way. Buy some extra half-gallon bottles for barter and charity. If you can afford it, buy a “Big Berky” British Berkefeld ceramic water filter. (Available from Ready Made Resources and several other Internet vendors. Even if you have pure spring water at your retreat, you never know where you may end up, and a good filter could be a lifesaver.)

Food Storage List
See my post tomorrow which will be devoted to food storage. Also see the recent letter from David in Israel on this subject.

Food Preparation List
Having more people under your roof will necessitate having an oversize skillet and a huge stew pot. BTW, you will want to buy several huge kettles, because odds are you will have to heat water on your wood stove for bathing, dish washing, and clothes washing. You will also need even more kettles, barrels, and 5 or 6 gallon PVC buckets--for water hauling, rendering, soap making, and dying. They will also make great barter or charity items. (To quote my mentor Dr. Gary North: “Nails: buy a barrel of them. Barrels: Buy a barrel of them!”)
Don’t overlook skinning knives, gut-buckets, gambrels, and meat saws.
Personal List
(Make a separate personal list for each family member and individual expected to arrive at your retreat.)
Spare glasses.
Prescription and nonprescription medications.
Birth control.
Keep dentistry up to date.
Any elective surgery that you've been postponing
Work off that gut.
Stay in shape.
Back strength and health—particularly important, given the heavy manual tasks required for self-sufficiency.
Educate yourself on survival topics, and practice them. For example, even if you don’t presently live at your retreat, you should plant a vegetable garden every year. It is better to learn through experience and make mistakes now, when the loss of crop is an annoyance rather than a crucial event.
“Comfort” items to help get through high stress times. (Books, games, CDs, chocolates, etc.)
First Aid /Minor Surgery List
When tailoring this list, consider your neighborhood going for many months without power, extensive use of open flames, and sentries standing picket shifts exposed in the elements. Then consider axes, chainsaws and tractors being wielded by newbies, and a greater likelihood of gunshot wounds. With all of this, add the possibility of no access to doctors or high tech medical diagnostic equipment. Put a strong emphasis on burn treatment first aid supplies. Don’t overlook do-it-yourself dentistry! (Oil of cloves, temporary filling kit, extraction tools, et cetera.) Buy a full minor surgery outfit (inexpensive Pakistani stainless steel instruments), even if you don’t know how to use them all yet. You may have to learn, or you will have the opportunity to put them in the hands of someone experienced who needs them.) This is going to be a big list!

Chem/Nuke Defense List
Dosimeter and rate meter, and charger, radiac meter (hand held Geiger counter), rolls of sheet plastic (for isolating airflow to air filter inlets and for covering window frames in the event that windows are broken due to blast effects), duct tape, HEPA filters (ands spares) for your shelter. Potassium iodate (KI) tablets to prevent thyroid damage.(See my recent post on that subject.) Outdoor shower rig for just outside your shelter entrance.

Biological Warfare Defense List
Disinfectants
Hand Sanitizer
Sneeze masks
Colloidal silver generator and spare supplies (distilled water and .999 fine silver rod.)
Natural antibiotics (Echinacea, Tea Tree oil, …)

Gardening List
One important item for your gardening list is the construction of a very tall deer-proof and rabbit-proof fence. Under current circumstances, a raid by deer on your garden is probably just an inconvenience. After the balloon goes up, it could mean the difference between eating well, and starvation.
Top Soil/Amendments/Fertilizers.
Tools+ spares for barter/charity
Long-term storage non hybrid (open pollinated) seed. (Non-hybrid “heirloom” seed assortments tailors to different climate zones are available from The Ark Institute
Herbs: Get started with medicinal herbs such as aloe vera (for burns), echinacea (purple cone flower), valerian, et cetera.

Hygiene/Sanitation List
Sacks of powdered lime for the outhouse. Buy plenty!
TP in quantity (Stores well if kept dry and away from vermin and it is lightweight, but it is very bulky. This is a good item to store in the attic. See my novel about stocking up on used phone books for use as TP.
Soap in quantity (hand soap, dish soap, laundry soap, cleansers, etc.)
Bottled lye for soap making.
Ladies’ supplies.
Toothpaste (or powder).
Floss.
Fluoride rinse. (Unless you have health objections to the use of fluoride.)
Sunscreen.
Livestock List:
Hoof rasp, hoof nippers, hoof pick, horse brushes, hand sheep shears, styptic, carding combs, goat milking stand, teat dip, udder wash, Bag Balm, elastrator and bands, SWOT fly repellent, nail clippers (various sizes), Copper-tox, leads, leashes, collars, halters, hay hooks, hay fork, manure shovel, feed buckets, bulk grain and C-O-B sweet feed (store in galvanized trash cans with tight fitting lids to keep the mice out), various tack and saddles, tack repair tools, et cetera. If your region has selenium deficient soil (ask your local Agricultural extension office) then be sure to get selenium-fortified salt blocks rather than plain white salt blocks--at least for those that you are going to set aside strictly for your livestock.

Hunting/Fishing/Trapping List
“Buckshot” Bruce Hemming has produced an excellent series of videos on trapping and making improvised traps. (He also sells traps and scents at very reasonable prices.)
Night vision gear, spares, maintenance, and battery charging
Salt. Post-TEOTWAWKI, don’t “go hunting.” That would be a waste of effort. Have the game come to you. Buy 20 or more salt blocks. They will also make very valuable barter items.
Sell your fly fishing gear (all but perhaps a few flies) and buy practical spin casting equipment.
Extra tackle may be useful for barter, but probably only in a very long term Crunch.
Buy some frog gigs if you have bullfrogs in your area. Buy some crawfish traps if you have crawfish in your area.
Learn how to rig trot lines and make fish traps for non-labor intensive fishing WTSHTF.
Power/Lighting/Batteries List
One proviso: In the event of a “grid down” situation, if you are the only family in the area with power, it could turn your house into a “come loot me” beacon at night. At the same time, your house lighting will ruin the night vision of your LP/OP pickets. Make plans and buy materials in advance for making blackout screens or fully opaque curtains for your windows.
When possible, buy nickel metal hydride batteries. (Unlike the older nickel cadmium technology, these have no adverse charge level “memory” effect.)
If your home has propane appliances, get a “tri-fuel” generator--with a carburetor that is selectable between gasoline, propane, and natural gas. If you heat your home with home heating oil, then get a diesel-burning generator. (And plan on getting at least one diesel burning pickup and/or tractor). In a pinch, you can run your diesel generator and diesel vehicles on home heating oil.
Kerosene lamps; plenty of extra wicks, mantles, and chimneys. (These will also make great barter items.)
Greater detail on do-it-yourself power will be included in my forthcoming blog posts.
Fuels List
Buy the biggest propane, home heating oil, gas, or diesel tanks that your local ordinances permit and that you can afford. Always keep them at least two-thirds full. For privacy concerns, ballistic impact concerns, and fire concerns, underground tanks are best if you local water table allows it. In any case, do not buy an aboveground fuel tank that would visible from any public road or navigable waterway. Buy plenty of extra fuel for barter. Don’t overlook buying plenty of kerosene. (For barter, you will want some in one or two gallon cans.) Stock up on firewood or coal. (See my previous blog posts.) Get the best quality chainsaw you can afford. I prefer Stihls and Husqavarnas. If you can afford it, buy two of the same model. Buy extra chains, critical spare parts, and plenty of two-cycle oil. (Two-cycle oil will be great for barter!) Get a pair of Kevlar chainsaw safety chaps. They are expensive but they might save yourself a trip to the emergency room. Always wear gloves, goggles, and ear-muffs. Wear a logger’s helmet when felling. Have someone who is well experienced teach you how to re-sharpen chains. BTW, don’t cut up your wood into rounds near any rocks or you will destroy a chain in a hurry.

Firefighting List
Now that you have all of those flammables on hand (see the previous list) and the prospect of looters shooting tracer ammo or throwing Molotov cocktails at your house, think in terms of fire fighting from start to finish without the aid of a fire department. Even without looters to consider, you should be ready for uncontrolled brush or residential fires, as well as the greater fire risk associated with greenhorns who have just arrived at your retreat working with wood stoves and kerosene lamps!
Upgrade your retreat with a fireproof metal roof.
2” water line from your gravity-fed storage tank (to provide large water volume for firefighting)
Fire fighting rig with an adjustable stream/mist head.
Smoke and CO detectors.

Tactical Living List
Adjust your wardrobe buying toward sturdy earth-tone clothing. (Frequent your local thrift store and buy extras for retreat newcomers, charity, and barter.)
Dyes. Stock up on some boxes of green and brown cloth dye. Buy some extra for barter. With dye, you can turn most light colored clothes into semi-tactical clothing on short notice.
Two-inch wide burlap strip material in green and brown. This burlap is available in large spools from Gun Parts Corp. Even if you don’t have time now, stock up so that you can make camouflage ghillie suits post-TEOTWAWKI.
Save those wine corks! (Burned cork makes quick and cheap face camouflage.)
Cold weather and foul weather gear—buy plenty, since you will be doing more outdoor chores, hunting, and standing guard duty.
Don’t overlook ponchos and gaiters.
Mosquito repellent.
Synthetic double-bag (modular) sleeping bags for each person at the retreat, plus a couple of spares. The Wiggy’s brand Flexible Temperature Range Sleep System (FTRSS) made by Wiggy's of Grand Junction, Colorado is highly recommended.
Night vision gear + IR floodlights for your retreat house
Subdued flashlights and penlights.
Noise, light, and litter discipline. (More on this in future posts--or perhaps a reader would like to send a brief article on this subject)
Security-General: Locks, intrusion detection/alarm systems, exterior obstacles (fences, gates, 5/8” diameter (or larger) locking road cables, rosebush plantings, “decorative” ponds (moats), ballistic protection (personal and residential), anti-vehicular ditches/berms, anti-vehicular concrete “planter boxes”, razor wire, etc.)
Starlight electronic light amplification scopes are critical tools for retreat security.
A Starlight scope (or goggles, or a monocular) literally amplifies low ambient light by up to 100,000 times, turning nighttime darkness into daylight--albeit a green and fuzzy view. Starlight light amplification technology was first developed during the Vietnam War. Late issue Third Generation (also called or “Third Gen” or “Gen 3”) starlight scopes can cost up to $3,500 each. Rebuilt first gen (early 1970s technology scopes can often be had for as little as $500. Russian-made monoculars (with lousy optics) can be had for under $100. One Russian model that uses a piezoelectric generator instead of batteries is the best of this low-cost breed. These are best used as backups (in case your expensive American made scopes fail. They should not be purchased for use as your primary night vision devices unless you are on a very restrictive budget. (They are better than nothing.) Buy the best starlight scopes, goggles, and monoculars you can afford. They may be life-savers! If you can afford to buy only one, make it a weapon sight such as an AN/PVS-4, with a Gen 2 (or better) tube. Make sure to specify that that the tube is new or “low hours”, has a high “line pair” count, and minimal scintillation. It is important to buy your Starlight gear from a reputable dealer. The market is crowded with rip-off artists and scammers. One dealer that I trust, is Al Glanze (spoken “Glan-zee”) who runs STANO Components, Inc. in Silver City, Nevada. Note: In a subsequent blog posts I will discuss the relationship and implications to IR illuminators and tritium sights.
Range cards and sector sketches.
If you live in the boonies, piece together nine of the USGS 15-minute maps, with your retreat property on the center map. Mount that map on an oversize map board. Draw in the property lines and owner names of all of your surrounding neighbor’s parcels (in pencil) in at least a five mile radius. (Get boundary line and current owner name info from your County Recorder’s office.) Study and memorize both the terrain and the neighbors’ names. Make a phone number/e-mail list that corresponds to all of the names marked on the map, plus city and county office contact numbers for quick reference and tack it up right next to the map board. Cover the whole map sheet with a sheet of heavy-duty acetate, so you can mark it up just like a military commander’s map board. (This may sound a bit “over the top”, but remember, you are planning for the worst case. It will also help you get to know your neighbors: When you are introduced by name to one of them when in town, you will be able to say, “Oh, don’t you live about two miles up the road between the Jones place and the Smith’s ranch?” They will be impressed, and you will seem like an instant “old timer.”

Security-Firearms List
Guns, ammunition, web gear, eye and ear protection, cleaning equipment, carrying cases, scopes, magazines, spare parts, gunsmithing tools, targets and target frames, et cetera. Each rifle and pistol should have at least six top quality (original military contract or original manufacturer) full capacity spare magazines. Note: Considerable detail on firearms and optics selection, training, use, and logistic support are covered in the SurvivalBlog archives and FAQs.

Communications/Monitoring List
When selecting radios buy only models that will run on 12 volt DC power or rechargeable nickel metal hydride battery packs (that can be recharged from your retreat’s 12 VDC power system without having to use an inverter.)
As a secondary purchasing goal, buy spare radios of each type if you can afford them. Keep your spares in sealed metal boxes to protect them from EMP.
If you live in a far inland region, I recommend buying two or more 12 VDC marine band radios. These frequencies will probably not be monitored in your region, leaving you an essentially private band to use. (But never assume that any two-way radio communications are secure!)
Note: More detail on survival communications gear selection, training, use, security/cryptography measures, antennas, EMP protection, and logistical support will be covered in forthcoming blog posts.

Tools List
Gardening tools.
Auto mechanics tools.
Welding.
Bolt cutters--the indispensable “universal key.”
Woodworking tools.
Gunsmithing tools.
Emphasis on hand powered tools.
Hand or treadle powered grinding wheel.
Don’t forget to buy plenty of extra work gloves (in earth tone colors).
Sundries List:
Systematically list the things that you use on a regular basis, or that you might need if the local hardware store were to ever disappear: wire of various gauges, duct tape, reinforced strapping tape, chain, nails, nuts and bolts, weather stripping, abrasives, twine, white glue, cyanoacrylate glue, et cetera.

Book/Reference List
You should probably have nearly every book on my Bookshelf page. For some, you will want to have two or three copies, such as Carla Emery’s "Encyclopedia of Country Living". This is because these books are so valuable and indispensable that you won’t want to risk lending out your only copy.

Barter and Charity List
For your barter list, acquire primarily items that are durable, non-perishable, and either in small packages or that are easily divisible. Concentrate on the items that other people are likely to overlook or have in short supply. Some of my favorites are ammunition. [The late] Jeff Cooper referred to it as “ballistic wampum.” WTSHTF, ammo will be worth nearly its weight in silver. Store all of your ammo in military surplus ammo cans (with seals that are still soft) and it will store for decades. Stick to common calibers, get plenty of .22 LR (most high velocity hollow points) plus at least ten boxes of the local favorite deer hunting cartridge, even if you don’t own a rifle chambered for this cartridge. (Ask your local sporting goods shop about their top selling chamberings). Also buy at least ten boxes of the local police department’s standard pistol cartridge, again even if you don’t own a pistol chambered for this cartridge.
Ladies supplies.
Salt (Buy lots of cattle blocks and 1 pound canisters of iodized table salt.)
(Stores indefinitely if kept dry.)
Two cycle engine oil (for chain saw gas mixing. Gas may still be available after a collapse, but two-cycle oil will probably be like liquid gold!)
Gas stabilizer.
Diesel antibacterial additive.
50-pound sacks of lime (for outhouses).
1 oz. bottles of military rifle bore cleaner and Break Free (or similar) lubricant.
Waterproof dufflebags in earth tone colors (whitewater rafting "dry bags").
Thermal socks.
Semi-waterproof matches (from military rations.)
Military web gear (lots of folks will suddenly need pistol belts, holsters, magazine pouches, et cetera.)
Pre-1965 silver dimes.
1-gallon cans of kerosene.
Rolls of olive drab parachute cord.
Rolls of olive-drab duct tape.
Spools of monofilament fishing line.
Rolls of 10 mil "Visqueen", sheet plastic (for replacing windows, isolating airspaces for nuke scenarios, etc.)
I also respect the opinion of one gentleman with whom I've corresponded, who recommended the following:
Strike anywhere matches. (Dip the heads in paraffin to make them waterproof.)
Playing cards.
Cooking spices. (Do a web search for reasonably priced bulk spices.)
Rope & string.
Sewing supplies.
Candle wax and wicking.
Lastly, any supplies necessary for operating a home-based business. Some that you might consider are: leather crafting, small appliance repair, gun repair, locksmithing, et cetera. Every family should have at least one home-based business (preferably two!) that they can depend on in the event of an economic collapse.
Stock up on additional items to dispense to refugees as charity.
Note: See the Barter Faire chapter in my novel "Patriots" for lengthy lists of potential barter items.
