Once you consider your first need, you must prioritize the remainder. You can survive three weeks without any type of food, but you will not last too much longer than three days if you have no water. Thus, water becomes the next need you must address. Before food, you will likely want to find shelter as well since you will need somewhere relatively safe for the night.
This group stresses being able to stay alive for indefinite periods in life-threatening wilderness scenarios, including plane crashes, shipwrecks, and being lost in the woods. Concerns are: thirst, hunger, climate, terrain, health, stress, and fear. The rule of 3 is often emphasized as common practice for wilderness survival. The rule states that a human can survive: 3 minutes without air, 3 hours without shelter, 3 days without water, 3 weeks without food. 
In the early ’80s on a job for the State Department to reinforce U.S. embassies and consulates following the 1983 Beirut barracks bombings, Pense says he and other government contractors around the U.S. converged on CIA headquarters at Langley, Virginia. The consortium of engineers traded notes and decided that the U.S. power grid was vulnerable. Inadequate, Pense says, compared to everything that’s been hung on it, and that was three decades ago. Three high-altitude electromagnetic pulses (EMPs) could take the whole thing down. Like New York City’s 1977 blackout, looting and pillaging would rule the streets, and that’s if they can get the lights back on quickly enough—if the power stays off for too long, order is lost forever.
What programs like Doomsday Preppers have accomplished, or at least contributed to, is turning sometimes well-informed, sometimes totally unwarranted paranoia into a booming prepper-industrial complex. Each year, swap meets pack hundreds of convention centers and fairgrounds across the nation—they’re like camping shows with a dose of military surplus and hands-on instructional sessions. The September 2017 Kansas City Survival Expo & Gun Show, for instance, had tips on seed saving, “Overcoming 900 Health Diseases” and “A Devastating Street Self-Defense System.” The latter was taught by Norman Cantwell, who inspired Patrick Swayze’s character in Roadhouse. You get the feeling that he and Steven Seagal would be friends.
“Hell yeah [we had fun making it]. It was surreal. I met [the Creative Control] guys through Shipes. They’re part of the team, and they’re like genuine, good guys. Those are my homies, Coodie and Chike. We were coming up with ideas as we were going along [with the masks from Urban Outfitters and different shots to use], so it was perfect synchronization.”
Food supplies in a bug-out vehicle include hundreds of pounds of wheat, rice, and beans, and enough honey, powdered milk, canned goods, bottled fruit, vitamins, dehydrated fruits and vegetables, salt, pepper, spices, and oil for several months. In addition, the kits often contain high-calorie energy bars, a cooking kit, utensils, liquid soap, and towels. The water supplies may include bottled water, filtering kit, bottles, collapsible water containers, and chlorine bleach for water purification. Food preparation and washing equipment may include items such as a grain grinder, a bread mixer, a strainer, a manual can opener, a steam canner with canning jars and O-rings, cutlery, knives, an electric 12-volt cooler icebox, kerosene lamps and heaters, kerosene or propane stoves, extra fuel, a clothes wringer, a foot-operated treadle sewing machine, and an electric hot plate (which would require an inverter to operate off a car battery).
One of that era's icons remains — a massive underground bunker designed to protect all 535 members of Congress and their aides against nuclear war. Dug into the Allegheny Mountains at the Greenbrier resort in White Sulphur Springs, W.Va., it once had 75,000 gallons of water, a power system, medical and food services, 30-ton blast doors, art of the last days of Pompeii and a mural of Washington scenery that was capable of changing leaves on the trees, depending on the season.
