I picked up the book on a friend's recommendation after I expressed my fears about camping in black bear country. What a fascinating book; the author essentially acclimated his presense to three generations of black bears, allowing him to observe their behaviors and habits.
After reading this book, I'm really not afraid of black bears anymore; I know now to make a lot of noise when I walk through the woods (to avoid surprising them). I don't have a dog (most black bear attacks on human are, in fact, provoked by dogs). And I will make sure never to sleep with doughnuts in my tent.
The book tends to get a little tedious and repetitive towards the end, although he does keep things fresh with some interesting stories and insight.
