Yishan Wong, an early Facebook employee, was the C.E.O. of Reddit from 2012 to 2014. He, too, had eye surgery for survival purposes, eliminating his dependence, as he put it, “on a nonsustainable external aid for perfect vision.” In an e-mail, Wong told me, “Most people just assume improbable events don’t happen, but technical people tend to view risk very mathematically.” He continued, “The tech preppers do not necessarily think a collapse is likely. They consider it a remote event, but one with a very severe downside, so, given how much money they have, spending a fraction of their net worth to hedge against this . . . is a logical thing to do.”
Preparing for an emergency is different for every family. Naturally, buying nutrient-rich foods and having ways to store and purify water is the first step for everyone. After that first step, deciding what type of supplies and gear to focus on is a personal journey depending on your preparedness goals. Think of your emergency supply as an investment in the health and safety of your family during a crisis.

And what better place to prepare than the Ozarks? Strafford got 47 inches of rain last year; the mean temperature was a mild 59 degrees. The Springfield Plateau has a 200-foot-deep aquifer for when rainwater gets scarce. The region is largely insulated from natural disasters—save the odd tornado or benign rumbling from the Bootheel’s New Madrid Fault Line—and the low population density of like-minded folks means preppers, survivalists and homesteaders get left alone. A Lebanon real estate agent tells me remote acreage is an increasingly hot commodity for city dwellers eager to go native. Conversations with locals and time spent on survivalism forums reveal a religious cohort who believe the Ozarks are God’s country—sacred ground upon which one can wage a last stand against the sins of a rapidly globalizing world.

SOG made their shovel practical survival gear by cutting back its length to a manageable 18 ¼” and its weight to an equally manageable 24 ½ ounces. It folds up to a mere 1 foot long and can be easily strapped to the exterior of any decent sized backpack. The SOG shovel also boasts a row of thick rugged teeth along the side for hacking and cutting underbrush or harvesting wood for your fire. The blade can also be rotated and used as a pick or a hoe to do more precise clearing. All in all this is a piece of survival gear you won’t want to do without.
Although there is a general public policy debate over whether the world's supply of oil reserves has peaked and the need for alternative fuels, this group believes that peak oil is a near term threat to Western civilization,[42] and take appropriate measures,[43] usually involving relocation to an agriculturally self-sufficient survival retreat.[44]
When bands of marauders start roaming the streets, how are you going to keep them out? Tear down a few walls, says Timothy Ferraro, a twenty-five-year construction veteran who's thought about this situation plenty while watching The Walking Dead. "Assuming the attackers don't have a battering ram, you should be able to keep them out using the lumber and drywall already in your home," he says.
