There are mornings that frozen, crunchy leaves make a stealthy approach impossible. I try to sound like a deer on those days, just a matter of changing the cadence of the walk. I think it's worked... When I am set up on the ground to rattle, there is nothing stealthy about it. One time, Sean and I set up to rattle on a frosty ridgetop. Eventually, he climbed out of his tree, ran around in circles grunting and tromping all over the place before quietly climbing back up to his stand. Honestly, I've never hear anything that sounded more like a buck chasing a doe... Nothing came in, but I appreciated his efforts, and in that hill country set up where hearing is far easier than seeing, I'm sure it's a method that would work if used again.
