Look at the wind through the animals eyes, alot of there sense are slightly alterd so they have to go into overtime, sight, smell,
motion is everywhere, Indeed you can get away with mistakes from yourself. During this time I have found that the deer are either gone before you see them or your going to step on them, It is an advantage for us, you wont see a ear flicker, or a tail move, but you can bett you will get close. Keep your eyes sharp and be ready.
