Fred Bear's Field Notes and Bows on the Little Delta are both 'must' reads. I bought two first editions of Field Notes when they first came out and had Mr. Bear sign them. Gave one to a friend's son on his 25th birthday. The other one sits on my night stand and I re-read a chapter or two every few weeks. Same with Bows on the Little Delta.
I recently picked up a - first edition signed copy of Fred Bear's Field Notes on Amazon for $20.00. When I think of it, I do a search on those sites for specific bowhunting books - and every so often you can really find a bargain. I pick them up and save them for graduation gifts, birthday gifts, etc. Talk about bargains, several years ago, I picked up a first edition Howard Hill, Wild $5.00 - should have bought a lottery ticket that day too . . .
