DBT, that's scary stuff. I had a cougar stalk me last fall for a good twenty minutes. It was damn scary, and I had a gun in my hand. The thing is it was in thick bush and I could never get a shot at him if I needed to, I gave a warning shot but that didn't help and I figured I should save the last two shots. I'm sure many people have been stalked and just don't know it, but this one was making a throaty growl, deep breathing sound the whole time. He wanted me to know I was being followed.
