Another older buck came back. Took a 35 yd shot. Looked to me like he squatted and rolled away from the arrow counter-clockwise from the sound of the string. Barely spooked him, taking about fifteen steps. He looked around a bit and went back about his corn hoovering, then finally moving within 15 yds. I couldn't draw on him, plus I'm silhouetted (sun behind me). He spooked a bit again and casually walked off. So these bucks approached the feeder from several avenues but all have exited the exact same route.
Staying put until 2.
