PSM once reported on a Cornish family’s two week experimental stay in their own fallout shelter – cut off from the outside world, role-playing a new life after the annihilation of civilisation. Robert and Margaret Farmer, along with their 11 year-old daughter Sarah, emerged triumphantly at the end of the experiment, which PSM described as a “complete success”. It did record, however, that “Sarah was a little bored around day three”.
Over the years, Huffman has become increasingly concerned about basic American political stability and the risk of large-scale unrest. He said, “Some sort of institutional collapse, then you just lose shipping—that sort of stuff.” (Prepper blogs call such a scenario W.R.O.L., “without rule of law.”) Huffman has come to believe that contemporary life rests on a fragile consensus. “I think, to some degree, we all collectively take it on faith that our country works, that our currency is valuable, the peaceful transfer of power—that all of these things that we hold dear work because we believe they work. While I do believe they’re quite resilient, and we’ve been through a lot, certainly we’re going to go through a lot more.”
Adherents of the back-to-the-land movement inspired by Helen and Scott Nearing, sporadically popular in the United States in the 1930s and 1970s (exemplified by The Mother Earth News magazine), share many of the same interests in self-sufficiency and preparedness. Back-to-the-landers differ from most survivalists in that they have a greater interest in ecology and counterculture. Despite these differences, The Mother Earth News was widely read by survivalists as well as back-to-the-landers during that magazine's early years, and there was some overlap between the two movements.
Survivalists' concerns and preparations have changed over the years. During the 1970s, fears were economic collapse, hyperinflation, and famine. Preparations included food storage and survival retreats in the country which could be farmed. Some survivalists stockpiled precious metals and barterable goods (such as common-caliber ammunition) because they assumed that paper currency would become worthless. During the early 1980s, nuclear war became a common fear, and some survivalists constructed fallout shelters.

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.[citation needed]

You can tour this slice of underground history today. After the Southwicks visited the bunker recently, they said they felt even more strongly about the need to prepare. Their family reflects a new preparedness instinct that has been growing since the 9/11 terrorist attacks. After that shock, the government urged people to store food, buy duct tape and roll water barrels into their basements.

Like any emergency kit, the Pocket Survival Pak — which was developed by Doug Ritter, founder of the survivalist website Equipped To Survive — can help lost or injured explorers signal helicopters and planes, start fires, boil water, melt snow for water, catch fish, navigate through the woods, trap small animals, perform rudimentary first aid, and repair damaged gear.
Religion, however, has everything to do with survivalism—there are things about your faith that affect the way you live, Fletch says, offering me an example. “Today, a great deal [on the menu] was the special you had,” he says. “Every one of the specials had pork in it. Well, depending on your belief system and where you’re coming from, Dan, you could’ve made several decisions about me.” He’s right; I could’ve thought he assumed the breakfast was on me, so he ordered the most expensive dish on the menu. And those assumptions, he says, can break up a group. “If 99 percent of the people in your group don’t eat pork, and you bring in some person eating a ham sandwich next to you, that’s going to cause some conflict.” 
James Patrick Douglas, a man of the land in Maine, shows off homesteading techniques he believes will become necessary based upon overpopulation fears; Larry Hall turns an underground missile silo into a bunker to make sure his family is safe during any event; Becky Brown (of Grab n Go Food Storage) is making sure she and others are ready for martial law.
When I started putting together my first survival kit, I just collected whatever weird stuff I could find—like tablets that would protect my thyroid from nuclear fallout. My mindset changed when my first daughter was born. I realized I needed a more practical end-of-the-world plan, with equipment that would be useful for things that might actually happen. Nuclear war is probably not in store for 2018, and if it is, I’ll just open a window. I don’t want to live through that.
