Moose,
It works for turkeys, but I doubt it would ever work on a old buck. If their are hay bales around, well that may make a difference. Youd have to cover the blind with hay though. I have my blind brushed in real good with sneaky leaves, but i still have deer that lok at it. Must of the time they dont care. Id try and use the blind, where you think they are coming out at. Get it close as you can and get right on the field edge. Hopefully you have something very thick to use as a backdrop.
Good luck, hunting from the ground is AWSOME.
