I have seen more aggression from Black Bears. One of my friends is bad luck when it comes to bears. He has been bluff charged, had them stand up and start puffing and popping their jaws. Sometimes it's the same bear that I just passed minutes before or after him. They tend to ignore me or at least tolerate me. But not him. Maybe I'm being mistaken as one of them. I may need to shave some more and shower better.
