After the quake in Japan and living near the Madrid fault line I would like to put together a good BOB I am place in my car. I am going to have one at home too put that's going to take more time to put together. At any rate what I was wondering is there a good type of food and water container that will hold up fine in heat, like the trunk of a car in 95 degree summer heat without spoiling or ruining it? I understand it won't last as long and changing out BOB food is no big deal. Also as far as water it doesn't seem like a good idea to place plastic containers in heat like that but what about stainless steel with a plastic and rubber lid, are there any ill affects heat would cause?
