The EDC bag thread got me thinking. Actually, this is something I've been thinking about for a while. I have a supply of emergency food at the house, but I'd like to keep some in my truck as well. What could I put in there that would be stable in the heat and cold? I'm in north Texas, so the summers are hot. 100 degrees are the norm, with temps inside a vehicle being much higher. It can also get cold here. Nothing extreme, but I'd need something that could withstand freezing temps. Will MREs handle this job? If so, I imagine they'd have to be replaced more frequently than when stored in a climate controlled house.
