Personally, I'm putting up quite a bit of canned foods in the basement. They are cheap enough to add another armload to the shopping cart, and they are already hydrated. The way I estimate it is that they are a bit heavier, but just as versatile as military MRE's. I also think that home canning is great if the normal precautions are observed. I sure hope that my kids will eat canned beets if the SHTF!!
