I'm a little nervous of the same thing Hobbit. I didn't used to be....but I seem to be now.
I haven't been attacked, but we rescued a lady who was about to be attacked once. It was scary.
There was a series of switchbacks winding down from a cabin we were staying at, to the lake. (Alta Lake) She had walked right by two cubs playing between the two roads. She had rounded the next hairpin turn and was heading down the road that would have put her between the cubs and the mama...(who we had just spotted) charging towards her. We hopped in our van and drove as fast as we could down the twisty road and pulled up to her...threw open the side door and dragged her in with seconds to spare. I think she was more frightened of us for a few moments, until she realized what was going on.
