9 out of 10 blacks aren't looking for trouble. They don't come in that order, but they will avoid you for the most part. I hunt in grizz and black terrain, and there are cats everywhere. A 375 H&H is my companion, because you never know. I have seen lots of them, but never had a problem with any of them. If a bluff charge ever happens, I guarantee that I will have a new rug. Anything that outweighs me by 500 pounds isn't going to get the chance to get close enough to maul and chew my old bones. Just relax and keep your eyes open.
