...and also, store-bought canned foods last a very long time - far beyond their stamped dates. I’ve eaten them 4 or 5 years out without no effect on quality, and I don’t even make an effort to store them properly (i.e., keep them cool). You can find articles talking 20 to even 50 years out.
I fully agree.... But I think a fully equipped canning outfit is extremely important to have on hand so one can protect what is scavenged after SHTF...
Also LOTS of books on wild eatables...
