The place i bow hunt has a trail that runs right under my stand and the deer will never even step across it where i cross. As soon as they hit the spot where i cross the nose hits the ground for a minute, then they either turn around or circle way around it. My boots are rubber and i never wear them except in the woods,not even in the car. Also last year i shot a deer and he ran about 20 yds up the trail and died and for two weeks after that every deer i saw stopped and smelled that spot. After I witnessed that i knew there's no way to fool them! I think some are just more "spooky" than others.
