You don't have to be some fringe lunatic to be a prepper. A lot of perfectly level headed folks are doing it. And you don't have to dig a big hole in the yard and stockpile it. IMHO everyone should have a "go" bag and a plan to egress, or exit, their home; especially a RV. Have undies, toothpaste, a bottle of water or two, medications, etc. (about a weeks worth) in a bag, ready to go. Have all your important papers in one place; we have a portable fire proof safe. There is more than the apocalypse to prep for. We have gate guards that have had to abandon their RV for all sorts of reasons; from floods to storms. We had to evacuate a gate due to a methane leak after the BOP failed. At the very least I would like for everyone to increase their situational awareness. Have a plan to get out should something happen. Finally, check ALL of your detectors and replace their batteries regularly.
