i hate ta be a stick in the mud...but aint that what a climber is for, to have your scent go over the top of the deer when the wind blows?
i have had deer come right at me from down wind and never seen me, walk right on by. (when in a tree stand)
granite, if you are in a tree, and to one direction of you is land as high as you are, then thats basically being on the ground. imo
