I'm not crazy about the Mapping Trophy Bucks book. There's definitely no harm in reading it, but I think that book is way to regional in its advice and, though it claims to be very specific, it seemed very general to me. I'd give the book a C, C+ at best.
I suppose it depends on where you are at in your understanding of terrain and the way deer use them. If you have a difficult time identifying funnels or are relatively new to hunting, the book could serve as a decent introduction. For the intermediate to experienced hunter, not so much. I didn't see much of anything in the book that a walk in the woods in January wouldn't tell you about how the deer use terrain and I do not recall seeing much actual advice on how specifically targeting "trophy bucks" as the title implies. The book should have been called "Deer Hunting and Topography in the Midwest."
