I've been blind-rattling and rattling when bucks are present the past few days and they haven't really paid too much attention to it at all. They will look, but, I think by this time of the year they are afraid of getting their butt kicked even more than it already has. These were smaller bucks that I was rattling to, btw. I just wanted to see what their reaction would be. Maybe it would be different if you happened upon the dominant buck in the area searching for that last doe in heat... I imagine he wouldn't hesitate to come running in unless he's had a bad experience in the past with a hunter rattling to him.
