I have that one as well. "Trophy Blacktails The Science of the Hunt" by Scott Haugen was the first BT book I picked up and the things I learned from it I say is what helped me harvest deer since. It is a good read and he presents it well. He shares stories and what works for him but wont really say anything is a dead set rule, haha, guess that means he really does know blacktails haha. "Hunting Blacktail Deer" by John Higley is a good one too. Cameron R. Hanes has a lot of good info in his book and DVD as well. I was so glad when I was able to start finding these books and such considering a lot of the folks I have hunted with are the drive the roads and just sit on clearcut hoping to get lucky types.
