would you want those books even if they where free?
well i'd want some of the pages and photo's out of them at least. :-D
stuarts right that the problem lies with the stuff that is just plain wrong. if you don't know enough to sort the good info from the bad, you're better off without.
mcmanners' book for example, has some great gems of info. the dioramas showing what to look for in a campsite for example. his jungle pole bed pics are good. (they ought to be!) he covers a wide range of info on available kit. there're photos of him in a tiny leanto with light shining through the very sparse thatch, bit crap if it rains, flint lined fireplaces, potentially very dangerous, and hugh with a dozen different things round his neck on bits of string, just silly really. there was a survival gameshow, "the bare necessities" where it was obvious that he could do it properly. i don't doubt that he knows his stuff. his "falklands commando" is a great read btw.
chris ryans book has the interesting if not very well explained photos of him dispatching a sheep. as far as i can tell there's no reason to give barry davies books room on the shelf at all (imho).
cheers, and.
