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.
About a month after I left meetup 2.0 at Pizza Hut, former attendee Garland Fitzhugh called to tell me it’s become more of an ‘eat-up’ than a prepper meetup—fair, considering there’s been no local calamity to keep the survivalist group on its toes. Allen emails meeting suggestions to a prepper listserv, asking them to focus on prepping situations they can actually influence. He may as well type in Wingdings. A former Navy technician, Allen spent most of the meeting on his phone; his ears only perk up when Andrew: says something about naval intelligence that piques his interest. “I try not to do that too much,” he tells me later.
This obviously means you’ll have to balance your use of redundant items with your carrying capacity. However, you can address both of these competing forces by trying to bring along items that serve multiple purposes. This way, you aren’t really bringing items that are duplicates of each other, but you still benefit from having some backup options. For example, duct tape is often included to repair clothing or camping gear, but you can also use it as a band-aid in a pinch. Safety pins are another good multi-purpose supply, as they can be used for clothing repairs, bent into fishhooks or used to sew up a wound if need be.
In both his book Rawles on Retreats and Relocation and in his survivalist novel, Patriots: A Novel of Survival in the Coming Collapse, Rawles describes in great detail retreat groups "upgrading" brick or other masonry houses with steel reinforced window shutters and doors, excavating anti-vehicular ditches, installing warded gate locks, constructing concertina wire obstacles and fougasses, and setting up listening post/observation posts (LP/OPs.) Rawles is a proponent of including a mantrap foyer at survival retreats, an architectural element that he calls a "crushroom".
Wearing the wrong attire: Heading out into the woodlands and wearing the wrong clothes and shoes is definitely looking for disaster. If it’s too cold outside in wintry weather and you’ve dressed lightly, you’ll end up with hypothermia or frostbite. Meanwhile, if its summer and your wearing layered clothing, you’ll increase the likelihood of a heat stroke on a hot day.
Is it stereotypical that the AARP crowd would be the ones to spend three hours talking about metal detectors and canning and caving at a Pizza Hut on a Monday night? Probably, but that’s what I bore witness to in this event room; its combination of exposed wood and stock-photo decor felt like an Olive Garden inside a pirate ship. Up front, the scraggly white-bearded, Bad Santa–lookalike Andrew: rested one foot on a chair, gripping the mic, just like Randall said he would be.
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. 
Preppers can learn a lot from studying military exercises. Take your preps to the next level by practicing actual off grid survival. Renting a remote cabin for a few days or even an RV motorhome or trailer can help prepare your family in advance for an actual bug out -- should we ever face a national catastrophe.

In addition, the kits may contain typical individual "survival kit" items, such as nylon tarps, extra clothes and coats, blankets, sleeping bags, matches or other fire starting equipment, a compass and maps, flashlights, toilet paper, soap, a pocket knife and bowie knife, a fishing kit, a portable camping stove, a power inverter, backpack, paper and pencil, a signaling mirror, whistle, cable saw, bleach, insect repellent, magnifying glass, rope and nylon cord, pulleys, and a pistol and ammunition.
Before fire season, move combustibles away from your house. Fences and dry vegetation give fires a place to grow, says Jonathan Cox at Cal Fire, California’s Department of Forestry and Fire Protection. Hosing down your house won’t help much, either, he says: “The way a lot of these homes burn is through something called ember cast, when embers from the fire fly over and drop little fires everywhere. With a huge ember cast, hosing down your house doesn’t do much.”
