One of the bucks i been trying to kill was at the feeder five minutes after i left. I got out of the shooting house, walked about 75yds across my foodplot, took a pic of the coyote with flash, and walked back and to the truck. The does never left the feeder, the buck and a spike was there five minutes later. Crazy stuff. I wasnt even trying to be quiet. I guess they know when you cant see them.
