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".
Another concern when you’re lost in the wild is where to procure potable water. Sometimes there will be bubbling streams of crystal clear water rolling down wooded hillsides to fill your water bottle and sometimes you’ll have little more than a stagnant pool standing between you and dehydration. The LifeStraw Personal Water Filter is survival gear that can turn that stagnant pool into a lifesaver.
A: There’s a lot of overlap between the above question and this one but basically once you have your survival gear separated into different categories you’ll want to distribute it in the exterior pockets of the backpack where it can be easily accessed in an emergency. The MOLLE survival gear system devised by the armed forces for combat troops takes a modular approach to organization that’s also extremely flexible and allows you to configure your supply load in a way that makes the most sense for you. Rows of nylon webbing are distributed across a vest that’s worn under the backpack. You’re then able to attach various MOLLE compatible accessories and pouches – in this case containing your survival gear – to the vest. Additional pouches can be attached to webbing on the exterior of the backpack as well.
Earthquakes, tornadoes, and hurricanes can cause you to leave your home or even be trapped there. Roads could be blocked due to fallen trees, power lines, or even damaged earth from the natural disaster. Rescue crews can not be in all places at once. You may have to wait it out for quite a while before its over. You won't be able to go to the store or to the corner market.
