Food supplies in a bug-out vehicle include hundreds of pounds of wheat, rice, and beans, and enough honey, powdered milk, canned goods, bottled fruit, vitamins, dehydrated fruits and vegetables, salt, pepper, spices, and oil for several months. In addition, the kits often contain high-calorie energy bars, a cooking kit, utensils, liquid soap, and towels. The water supplies may include bottled water, filtering kit, bottles, collapsible water containers, and chlorine bleach for water purification. Food preparation and washing equipment may include items such as a grain grinder, a bread mixer, a strainer, a manual can opener, a steam canner with canning jars and O-rings, cutlery, knives, an electric 12-volt cooler icebox, kerosene lamps and heaters, kerosene or propane stoves, extra fuel, a clothes wringer, a foot-operated treadle sewing machine, and an electric hot plate (which would require an inverter to operate off a car battery).
Regardless of whether everything is going swimmingly or you’re lost in a whiteout above tree line your boots are one of the most important pieces of survival gear you have. You need them to stand up to the elements and keep your feet dry and comfortable. Irish Setter Men’s Waterproof Hunting Boot is a fine example of the state of the bootmaker’s art.
In addition, the kits may contain typical individual "survival kit" items, such as nylon tarps, extra clothes and coats, blankets, sleeping bags, matches or other fire starting equipment, a compass and maps, flashlights, toilet paper, soap, a pocket knife and bowie knife, a fishing kit, a portable camping stove, a power inverter, backpack, paper and pencil, a signaling mirror, whistle, cable saw, bleach, insect repellent, magnifying glass, rope and nylon cord, pulleys, and a pistol and ammunition.
Based on this crude but honest assessment of the general public's affinity for the common bicarbonate, you'd be surprised by how much survivalists are into it (#2 on the list of "things for preppers to hoard"). They must expect some pretty serious hankerings for tasty leavened baked goods, or they have extensive phobias about the funkiness of their nuke survival backup plans.
In both his book Rawles on Retreats and Relocation and in his survivalist novel, Patriots: A Novel of Survival in the Coming Collapse, Rawles describes in great detail retreat groups "upgrading" brick or other masonry houses with steel reinforced window shutters and doors, excavating anti-vehicular ditches, installing warded gate locks, constructing concertina wire obstacles and fougasses, and setting up listening post/observation posts (LP/OPs.) Rawles is a proponent of including a mantrap foyer at survival retreats, an architectural element that he calls a "crushroom".
Another concern when you’re lost in the wild is where to procure potable water. Sometimes there will be bubbling streams of crystal clear water rolling down wooded hillsides to fill your water bottle and sometimes you’ll have little more than a stagnant pool standing between you and dehydration. The LifeStraw Personal Water Filter is survival gear that can turn that stagnant pool into a lifesaver.
