I bought the book last year for a song and it is very thorough. It is chock full of information, but I honestly can't say it was super helpful-- I feel like a lot of it I was aware of (what they eat at certain times of the year, etc.) or was PhD level stuff over my head and not super helpful when it comes to hunting. If you're able to get it and read it (it's dry, but again, thorough) that's great-- but don't worry that there's some secret manual in Chapter 17 about how to hammer elk in the second week of September in there.
