I wouldn't go into bear county without at least a .44 mag. I don't think you want to use a knife, any knife, against a full sized bear. With that said, bears usually don't attack people. The main reason why you see bear attacks are when you get between her little baby bears. They are very protective animals, and will do anything to keep their offsprings safe.

My group came across one some years ago in NJ. We just slowly walk away from her while keeping an eye on the general direction. My friend said he will have to do something if she starts to walk closer. She didn't, which I'm glad because he's got a 30-06 aimming at her... We spotted her around 75 yards or so. The key is not let them get too close. Always know what is around you. If by any chance they get within 25 yards or less, best thing to do is probably make alot of sound like SHARP mention but also try to make yourself seen bigger than you are. hold your hands up high and scream yell, whatever.

I don't know how fast of a runner you are but I don't think I can out run an angry bear....so running wouldn't be an option... <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
