RE: butt kicked by a deer? or other big game?
I was nearly attacked by a black bear sow while spring turkey hunting last year. She and her cubs walked into my setup, and I got penned in between mama and the little ones. The one cub came in to about 2 feet from my right leg and finally picked me out.
Man oh man. That cub tried to run and got balled up in some brush and started bawling Mama was none too thrilled with me. I ran away, and she stopped charging once she was between me and the cubs. It all happened so fast, I don't even remember standing up and running.
I ran about 10-15 yards and she closed in to about 10 feet behind me, when I turned to fire. She stopped, which was a good decision for both of our sakes. She was about one step from taking three hevi-shots at point blank.
I'm just glad nobody else was with me, because some of my hunting buddies are slow and out of shape - which may have led to a different result.
