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”.
Three hours after I arrived, Andrew: senses it’s time to wrap up, but not before breaking into one last story about the Bigfoot footprints he keeps in the back of his car. The prints were collected in Arkansas in 1956, he says, and they belong to an adult male, a juvenile female and an adult female. He says he himself came from the “drug scene hillbillies” and that his ancestors had six digits. 
By his own estimate, Pense says there are a few thousand people in the Springfield area who have listened and who are ready. The preppers. Most don’t like to be called preppers because of the connotation that they’re crazy; Chicken Little wasn’t well-received by his people, either. Most don’t even like to talk about it, but a few of them do. So for three months toward the end of 2017, I sought out the doomsday survivalists to find out: Is it really crazy to live like the sky is falling?
The fears were different in Silicon Valley. Around the same time that Huffman, on Reddit, was watching the advance of the financial crisis, Justin Kan heard the first inklings of survivalism among his peers. Kan co-founded Twitch, a gaming network that was later sold to Amazon for nearly a billion dollars. “Some of my friends were, like, ‘The breakdown of society is imminent. We should stockpile food,’ ” he said. “I tried to. But then we got a couple of bags of rice and five cans of tomatoes. We would have been dead if there was actually a real problem.” I asked Kan what his prepping friends had in common. “Lots of money and resources,” he said. “What are the other things I can worry about and prepare for? It’s like insurance.”
When I visited Johnson, not long ago, at his office on Park Avenue South, he described himself as an accidental student of civic anxiety. He grew up outside Detroit, in Grosse Pointe Park, the son of a doctor, and he watched his father’s generation experience the fracturing of Detroit. “What I’m seeing now in New York City is sort of like old music coming back,” he said. “These are friends of mine. I used to live in Belle Haven, in Greenwich, Connecticut. Louis Bacon, Paul Tudor Jones, and Ray Dalio”—hedge-fund managers—“were all within fifty yards of me. From my own career, I would just talk to people. More and more were saying, ‘You’ve got to have a private plane. You have to assure that the pilot’s family will be taken care of, too. They have to be on the plane.’ ”
Stories like this, according to Charles, happen often when "sh—t hits the fan." One prepared person warns others in the run-up to a potentially dangerous event and others don't listen, expecting someone — the government or a friendly neighbor — to provide during a disaster. It's what Charles calls "the entitlement problem," a phenomenon talked about ad nauseam on prepper blogs and websites.
They are part of a burgeoning "prepper" movement that believes preparing for the end of civilization is more rational than ridiculing those who do. Once viewed largely as a practice by survivalists on the fringe, prepping has achieved cohesion and community in the Internet age through best-selling writers, bloggers, risk assessors, conspiracy theorists and companies that cater to preppers' needs.
If the fire is around you and you can’t escape, you don’t have many options, says Shane Hobel of the Mountain Scout Survival School. If there’s a pool or a pond nearby, jump in and try to wait it out there. Otherwise, if you have time, dig a trench that’s two to three feet deep and long enough for you to lie in. Soak a blanket in water, wrap it around yourself, and lie down in the trench. It’s risky, but at least you’ll have a chance.
