I've been fortunate enough to "seal the deal" for the most part during the last 14 seasons. The biggest thing that helped me to accomplish this was to place my stands in bottlenecks and funnels where the big ones almost had to enter. It's all about location. A few yards off one way or another can mean the difference between sucess and failure. The second biggest thing is to not hunt the stand if the wind is even the slightest bit wrong. If you let them know where you are, they will not come by you.
