Those hardcopy in the hand books will be priceless if SHTF in a big way, My "Redneck library", ( thats what my wife calls it) now consists of a little over 1/4 of a buried 40' conex. I have said it before, and I will again, Knowledge is power. I dont trust computers or disks to be able to survive useably in SHTF situation, but then I like what I can see, and trust in. written words are the way for me.
Your foresite into area specifics is right on in my book, I would love to catch a wels catfish, but a manual on them worthless in the area I am in. There are none here. Your spot on, as about area/ region specific.
