One of the “skills” every prepper should learn (and learn this week or next) is foraging for edibles in and around their homes. Search the library or order a book on Amazon…one with pictures…to learn which weeds provide vitamins and minerals and how to spot them (and their poisonous look-a-likes) in YOUR neighborhood. The day MAY come when that is ALL that is available to eat because the mice, rats, birds, cats and dogs have already been dispatched to feed hungry neighbors. Weeds are likely to still be around even after looters have torn out and dug up your gardens in search of food.
In the next decade Howard Ruff warned about socio-economic collapse in his 1974 book Famine and Survival in America. Ruff's book was published during a period of rampant inflation in the wake of the 1973 oil crisis. Most of the elements of survivalism can be found there, including advice on food storage. The book championed the claim that precious metals, such as gold and silver, have an intrinsic worth that makes them more usable in the event of a socioeconomic collapse than fiat currency. Ruff later published milder variations of the same themes, such as How to Prosper During the Coming Bad Years, a best-seller in 1979.
What’s the bare minimum you need to navigate across land? For most people, that would be a compass and map. A basic road map is sufficient to get a rough approximation of the lay of the land. More detailed relief maps can help plan for elevation and estimate possible water sources but they also take up more room in your pack. Waterproofed or laminated maps are also extremely helpful. Lensatic compasses are the most reliable for little money. If possible, a compass and protractor are also extremely helpful for route planning. Obviously, not as essential but nonetheless useful.
