One newsletter deemed by some to be one of the most important on survivalism and survivalist retreats in the 1970s was the Personal Survival ("P.S.") Letter (circa 1977–1982). Published by Mel Tappan, who also authored the books Survival Guns and Tappan on Survival. The newsletter included columns from Tappan himself as well as notable survivalists such as Jeff Cooper, Al J Venter, Bruce D. Clayton, Nancy Mack Tappan, J.B. Wood (author of several gunsmithing books), Karl Hess, Janet Groene (travel author), Dean Ing, Reginald Bretnor, and C.G. Cobb (author of Bad Times Primer). The majority of the newsletter revolved around selecting, constructing, and logistically equipping survival retreats. Following Tappan's death in 1980, Karl Hess took over publishing the newsletter, eventually renaming it Survival Tomorrow.
During his 45th Infantry Division, Pense taught field wiring, instructing G.I.s on setting poles and stringing wires to rig together a communications network from scratch. After the war, he was an electronics engineer in the private sector, sometimes on military contracts, learning the frailty of the nation’s power grid firsthand. On one government contract, he witnessed a nuclear warhead knock out power in Hawaii after detonating high above the Pacific.
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. 
“That’s a major problem,” says Gene Louis, a New Jersey expat who attended his first meetup in 2013 after moving to Springfield to begin ventures in real estate brokerage and digital marketing. Plus, Jersey is expensive, and he doesn’t like the fact that its residents don’t pump their own gas. “You don’t know what people are going to define as a threat, don’t know what people at survival meetings are going to talk about,” he says. “You can’t prepare for 100 percent of what’s on that list—well, you’d need to be Donald Trump to afford to.”
Don’t forget spices and nutritional supplements. Yes, you can plan a well-balanced diet with prepared foods, but not everyone has the same taste. Spices and herbs allow you to change up the flavor of the same basic ingredients for variety and interest. Vitamins and supplements are an important addition to your emergency supply stash. Choose nutrition bars, protein powder, or multivitamin capsules that support nutrition and boost natural immunity.
Fear of disaster is healthy if it spurs action to prevent it. But élite survivalism is not a step toward prevention; it is an act of withdrawal. Philanthropy in America is still three times as large, as a share of G.D.P., as philanthropy in the next closest country, the United Kingdom. But it is now accompanied by a gesture of surrender, a quiet disinvestment by some of America’s most successful and powerful people. Faced with evidence of frailty in the American project, in the institutions and norms from which they have benefitted, some are permitting themselves to imagine failure. It is a gilded despair.
For Mike Mester, civil unrest is just around the corner and he aims to get everyone ready; Colorado computer programmer Preston White has collected over 11,200 types of seeds and plans for biosphere living in a Fukushima-irradiated future while friends Shane and others provide supportive help; Riley Cook spends his days working close to home and with the prepper society building underground structures.
3. The water will slowly filter through the charcoal and drip out of the cap. Put a bandanna or another cloth over the hole to filter out any bits of charcoal. (If you’re experiencing intestinal distress—and you very well might be, since your body goes into different kinds of shock in these situations—eat a little bit of the charcoal. It’ll help bind you back up.)
