I almost had it one of those today, I was crawling through the tundra and brush trying to reach a moose and crawled up the side of a brush covered rock and stood her on one rear tire some how it it did not go over. My hunting partners were behind me in a P700 and they could not believe it did not go over. I reversed down the rock went around it and after about 200 yards decided there was no way we could get to the moose so we turned around and went back out.
I'll upload pictures when we get back to town.
