Sense we cannot predict what type of SHTF will happen, one needs to be somewhat prepared for as much common types of SHTF. The need for food, water, medical needs, warmth, is necessary in almost all cases of SHTF. In my youngest sons and my 72 hour bug out bag we got all the common things plus a few thing that are not common. Like a 2 Gig. flash drive sealed in a waterproof match container from wal-mart. I can hear it now, “why do you need a flash drive? There is not going to be any electricity or computers. Well We are storing all important documents on them such as photo copies of Driver license, Birth certificate, SS card, DD-217’s, important medical history. Paper copies will take up weight and space and possibly get damaged. A 2 gig flash drive costs about $10 U.S. at Wal-Mart, and the waterproof match container is about $2.50. Everything is on it including back ups of my sons on mine and back ups of mine on his. We have also put my vehicle registration and title on it along with all weapons serial numbers, makes, models, and cal. Because once a SHTF is over things will get somewhat back to normal and you may not have any of the documents because they were destroyed in a tornado or flood. This way you got something to go by.
