2003ish, I was sitting in a stand in a large pine tree overlooking a creek bottom from the hill. Seventy-five foot drop to the bottom @ 100yds. One week later I killed a 9pt, 6 year old bruiser from the same stand.
I had one of these fellers climb up, perch on the front of my stand and leap out after fly's. He would then climb back up and do it again. Probably did it 10 times during my sitting. Saw no deer but was amused and amazed for 4 straight hours.
