My buddy said the same thing once.I agreed at the time but now I would have to say that I don't have 2000 tv's or pictures hanging on my walls. I don't know if deer take inventory of the trees and see what is out of place. I think there is so much out your outline is just a fly on the wall. If you get busted it's because of smell or movement. Just my 2 cents.

Let's put it in perspective...in your world...
If you walked into your living room and your TV was shaped differently what would you do? If there was something on your wall that was out of place what would you do? You would know fellas!
Guys...the deer know when something is out of place...you are in their home...you are on their grounds....its just like in your home....you know when something is not in the right place...
