Part of the hunt to me is being on the same level as the animal. I wouldn't pass at the opportunity to hunt out of a tree stand though, the view you would get, the stealthyness of the ambush, the suprise to the animal standing below you, I could imagine that is a great rush in itself.
I've taken all my bowkills from the ground however, and you're right JT, it's exciting, and satisfying.
