I agree with the curiousity. I know a guy who always got a deer. No matter what, he filled his tag, and it kinda frustrated the circle of people that shared those woods.
The year I turned 17, I got a great pair of binos for a present. Perched on top of a hill, I saw him set up about 500 yards away. He took a regular black garbage bag, filled it with air with a twitch. He then tied it off on a branch so that any wind would make it move. About an hour later I watched a big old doe walk up to the bag head bobbin, foot stompin.
I asked him about it years later-he grinned and said " I wish I used my radio that day, that woulda had ya guessing". Seems he would also set up a transistor radio and let them come check that out too...
