One time, I was 30 plus feet high in a tree, watching some does steadily walk a trail that goes beneath me. I was completely motionless, against the tree with camo on and everything, and WASN' T even going to shoot. Yet the lead doe looked up at me when it was within 10 yards of my stand. That is odd, since it had to look up steeply at me from that close. She stopped and trotted away, other does in tow, only to come out about 40 yards behind me about 10 or 15 minutes later. That time, I decided not to wait for a buck, but to go ahead and fill my tag, and I popped the lead doe with my open sight muzzleloader in hopes it was the same one who saw me before. Of all my hunting experiences that was the most unbelieveable time I got busted. It was as though she had ESP or something...
