The increased inflation rate in the 1960s, the US monetary devaluation, the continued concern over a possible nuclear exchange between the US and the Soviet Union, and perceived increasing vulnerability of urban centers to supply shortages and other systems failures caused a number of primarily conservative and libertarian thinkers to promote individual preparations. Harry Browne began offering seminars on how to survive a monetary collapse in 1967, with Don Stephens (an architect) providing input on how to build and equip a remote survival retreat. He gave a copy of his original Retreater's Bibliography to each seminar participant.
That spirit of self-sufficiency runs through the history of American food culture. Lydia Maria Child’s 1829 manual The Frugal Housewife, one of the first American cookbooks ever published, instructed women to contribute to their family’s finances by making sure no scrap of food was wasted: “Nothing should be thrown away so long as it is possible to make any use of it, however trifling that use may be.” The Church of Jesus Christ of Latter-Day Saints* encourages members to keep a three-month food supply on hand at all times, and even sells dehydrated food products on its official website. This Mormon connection may be why Utah is such a freeze-dried food hub: Of 21 freeze-dried food companies I counted online, 16 were from the state, and Bedford told me she first learned about long-term food storage by reading blogs by Mormon women.
When bands of marauders start roaming the streets, how are you going to keep them out? Tear down a few walls, says Timothy Ferraro, a twenty-five-year construction veteran who's thought about this situation plenty while watching The Walking Dead. "Assuming the attackers don't have a battering ram, you should be able to keep them out using the lumber and drywall already in your home," he says.
