I thought that when you encounter a black bear that you are supposed to make noise to intimidate it. Is this not true? I have been running for 34 years and I know when I come across a loose large aggressive dog, the best thing to do is ignore it until it comes right up to you. When the dog is a few feet away turn and yell at it. I usually yell,"get back in you yard". It always works.
So what is the right thing to do when a bear confronts you as it did Bill?
