In southern Utah there is a small town that has quite a few apple orchards. An attempt was made to fence the deer out, with a 10' fence. Of course the deer were not fenced out. Anyway, I once jumped a buck on the inside of the fence and watched it clear the 10' fence. It was one of the most, if not THE most amazing feats of athleticism I have ever witnessed. The buck didn't even touch the fence on his way over it!
