My point still is that you can fool their eyes be it with camo or cover (or both) however, you will not fool their nose.

You can have a deer spot you but not recognize you as a threat due to camo or having good cover around/behind you.

BUT, if a deer catches the slightest bit of wind from you, your hunt is over. The nose is the only sense you cannot fool.

PS. My quote came directly from your post. It was not edited or altered and was exactly what you said.
