That edge of swamp tactic worked for me today, quite a bit of snow in the opens up here, watched the coyote work it's way along the edge of a beaver pond just inside the edge. It came in on my far right side, couldn't swing on it quick enough. Thought it would continue to work its' way towards the call, but seemed to vanish. Was about to give up and decided to hit pup distress, brought it right back into the same opening in the hemlocks, and there it fell. Thanks LARUEminati for the tip!
