Finelli sits across from me at the food court picnic table inside the Sam’s Club on Sunshine Street, where he requested we meet. The retired computer systems designer-turned–radio show host and homesteader has salt and pepper hair, wears a plaid shirt and jeans and carries a .45-caliber automatic firearm on his person (he won’t say where). Below his strong jawline hangs a leather bag full of crushed sapphire, meant to enhance his overall health. 
Survivalists maintain their group identity by using specialized terminology not generally understood outside their circles. They often use military acronyms such as OPSEC and SOP, as well as terminology common among adherents to gun culture or the peak oil scenario. They also use terms that are unique to their own survivalist groups; common acronyms include:
Charles started prepping nearly four years ago after reading Newt Gingrich's introduction to the science fiction novel "One Second After." In the introduction, Gingrich wrote about the possibility of a catastrophic electromagnetic pulse attack. Such an attack, he said, would "throw all of our lives back to an existence equal to that of the Middle Ages ... Millions would die in the first week alone." To hear a public figure like Newt Gingrich seriously lay out what he thought was a plausible scenario convinced Charles that he needed to prepare.
Individual survivalist preparedness and survivalist groups and forums—both formal and informal—are popular worldwide, most visibly in Australia,[93][94] Austria,[95] Belgium, Canada,[96] France,[97][98] Germany[99] (often organized under the guise of "adventuresport" clubs),[100] Netherlands,[101] New Zealand,[102] Russia,[103] Sweden,[104][105][106] the United Kingdom,[107] and the United States.[23]
“One misconception about prepping is that you’re always thinking there’s going to be some kind of epic disaster,” she told me over the phone from Virginia. “The most common disaster that we prep for, or that happens to us, is a financial problem.” A longtime single mother, Luther said her interest in food storage grew out of a period of “abject poverty” following the 2008 recession. Lisa Bedford, a Texas-based writer who runs the site The Survival Mom, told me she got into disaster preparedness around the same time, when she wasn’t sure if her husband’s construction business would survive the downturn. (Bedford also works as an independent consultant for Thrive Life, meaning that she promotes their products online, and receives a commission on purchases from customers she refers to the company, as well as a discount on products she buys herself.)
Nail your studs together in lengthwise pairs at a 90-degree angle to form braces. This makes them stronger. Then run three or four braces horizontally across every door, hammering the nails from above and below directly into the frame at a 45-degree angle. If you drive them straight in, they're easier to pop out when somebody kicks the door. Use more braces to secure the drywall over the windows. Try to use longer nails and leave a couple inches of each nailhead sticking out for easy removal. — Clint Carter
