Don't give them long to look at you. Get in there 30-45 min. before you think you'll be shooting. Plan your entrance out so you can stealth your way in. I've used a leaf blower before to totally clear the path. Seems to created such a ruckus that they flee without ever seeing why and come back that evening to check out what was up (you can tell by the tracks). Pick your day and don't miss. If you want to check and see what kind of bucks are there without any trouble at all put some thread across the trail high and low. When you return check it on the way in. Both will be broke for bucks, only the bottom for does. It works!
