Learn from each failure and you will find they occur less often. Alot can go wrong from the time you see a deer close and getting an arrow in it. That deer didn't clear the county but he did get educated, those older bucks are wary. Here's one of my storys. About 10 years ago I had a nice one come up past the tree right at dark on the first evening I hunted the stand. I missed him, just plain blew it. No excuses. When I missed he ran about 40 yards into the hardwoodsand looked around confused. I figured he wasn't too spooked and would be back. The season had three more weeks and I never saw him until the last morning of the season. I had three does below me and then hear a deer above me and there he is 35-40 yards away. Perfect, I'm right between him and the does. He just stared at them and grunted but would not come past the tree to them. This went on for 5 minutes and he eventually walked away. He didn't wind me he just didn't like it. I'd give him a week off and change locations on him. He is still there....either that or go find another buck..good luck
