I would think that the book, "Prudent Places" by Stan and Holly Deyo; would be a source of intelligent considerations to be looked at.

Usual disclaimer: I have no affiliation with Stan or Holly Deyo, EXCEPT that I bought Holly's book, "Dare to Prepare", and found it to be an excellent primer for the prep minded individual just starting out.
