So I get in there, circle downwind and get to about 175 yds out with a clear shooting lane through the trees. I set up behind a tree, got a perfect branch for a rest, I'm set. I'm there for about 10 minutes and a single shows up working his way in through the brush. It's almost to the clearing where the carcass is laying and a pair of ATV's come blasting down a forest road about 50 yards away.
I stayed til dark but never saw another flicker.
I might get to try again tonight, but the carcass won't have much left on it after today I'm afraid.
