Business for Hardened Structures, an engineering firm based in Virginia Beach, is up roughly 40% since 2005, co-owner Brian Camden says. Some of his clients buy gold and silver and other precious metals as a hedge against a possible collapse of the currency, and they want to be able to protect it and their families, he says. So his company designs ways to build underground bunkers, strengthen walls and improve security systems on homes.
According to Hobel, shelter is your first priority. Lay down cardboard and other materials to insulate yourself from the ground. (Even in summer, the ground can have temperatures that lead to hypothermic conditions.) Use tarps, blankets, pillows—whatever you can find—to build the shelter on that layer. It should be as low to the ground as possible, and you shouldn’t be able to sit up when you’re inside, Hobel says. Other than the airflow you need to breathe, block all openings to keep cold air from coming in. It’s a matter of conserving heat. A lot of people don’t realize that their bodies are heat sources, Hobel says. You’re almost 100 degrees. Trap that heat around you instead of letting it rise in a tall shelter, and you won’t need a fire to stay warm.
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.
Wetfire is a non-toxic product that won’t produce clouds of noxious smoke. All it takes is a tiny bit sprinkled on the camp stove to get it going even when the rain or snow is coming down in blankets. In survival situations many perish because they’re unable to create the warmth they need to counteract cold, wet conditions. Wetfire is pocket-sized survival gear that allows you to withstand nature’s worst. Wetfire has a 5 year shelf life and can be activated using any stormproof lighter or other sparking device.

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
