I have to admit when I first read the title "Getting a healthy diet after The Big One" I thought the "Big One" you were referring to was a heart attack...

On the serious side, I live in an area though cursed with it's share of backwards idiots most of which hold public office, is also blessed with a wide variety of wildlife and wonderful growing seasons.

Just gotta stock up on some multivitamins to cover those nutrients that we gotta import because they grow better elsewhere.
