For some good reading, especially if you're hunting out west or to Canada:
Bear Attacks: Their Causes and Avoidance
by Stephen Herrero
Bear Attacks: The Deadly Truth
by James Gary Shelton
Blindsided by Jim Cole
I read an animal attack book from the library years ago. One of the things that has stuck with me is that often times a mother can fend off animals with a broom! Our maternal instinct to protect can be very effective. But in reality, each situation calls for different reactions. Just hope that if it happens to you, you make the right move or lack there of.
