According to Hobel, shelter is your first priority. Lay down cardboard and other materials to insulate yourself from the ground. (Even in summer, the ground can have temperatures that lead to hypothermic conditions.) Use tarps, blankets, pillows—whatever you can find—to build the shelter on that layer. It should be as low to the ground as possible, and you shouldn’t be able to sit up when you’re inside, Hobel says. Other than the airflow you need to breathe, block all openings to keep cold air from coming in. It’s a matter of conserving heat. A lot of people don’t realize that their bodies are heat sources, Hobel says. You’re almost 100 degrees. Trap that heat around you instead of letting it rise in a tall shelter, and you won’t need a fire to stay warm.
In fact, one of the subjects specifically told Mills that "it’s not like on [National Geographic’s] Doomsday Preppers." They weren't preparing for the total collapse of society. They were getting ready to deal with a local collapse of services that might last a few months. It's less Armageddon and more Hurricane Irma—which hadn't hit yet while Mills was doing his interviews but has since suggested that preparing for a couple of months without key services may be badly underestimating needs. Prepper supplies would typically be enough to only hold out that long, and Mills said they often referred to these caches as "more than they'd ever need."
