Zombie apocalypse: Used by some preppers as a tongue-in-cheek metaphor[75] for any natural or man-made disaster[76] and "a clever way of drawing people’s attention to disaster preparedness".[75] The premise of the Zombie Squad is that "if you are prepared for a scenario where the walking corpses of your family and neighbors are trying to eat you alive, you will be prepared for almost anything."[77] Though "there are some... who are seriously preparing for a zombie attack".[78]

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).
Modern-day survivalists aren't generally regarded as the most sane people on the planet. A quick look at any one of the disturbingly common and frighteningly thorough shopping lists they post online drives home the fact that anyone who self-identifies as a "prepper" most likely went off the deep end a long time ago. Sure, it's fine to keep a few extra cans of food and cases of water around for an emergency, but if you start adding body armor and butt paste to your stash, you might want to tell George Miller that it's time to see other people.
Individual survivalist preparedness and survivalist groups and forums—both formal and informal—are popular worldwide, most visibly in Australia,[91][92] Austria,[93] Belgium, Canada,[94] Spain,[95] France,[96][97] Germany[98] (often organized under the guise of "adventuresport" clubs),[99] Italy,[100] Netherlands,[101] Russia,[102] Sweden,[103][104][105] Switzerland,[106] the United Kingdom,[107] and the United States.[22]
Articles on the subject appeared in small-distribution libertarian publications such as The Innovator and Atlantis Quarterly. It was during this period that Robert D. Kephart began publishing Inflation Survival Letter[5] (later renamed Personal Finance). For several years the newsletter included a continuing section on personal preparedness written by Stephens. It promoted expensive seminars around the US on similar cautionary topics. Stephens participated, along with James McKeever and other defensive investing, "hard money" advocates.
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.
Earthquakes, tornadoes, and hurricanes can cause you to leave your home or even be trapped there. Roads could be blocked due to fallen trees, power lines, or even damaged earth from the natural disaster. Rescue crews can not be in all places at once. You may have to wait it out for quite a while before its over. You won't be able to go to the store or to the corner market.
