It was in a tree about 6 feet up. I know of a place about 200 yards on the other side of an ash swamp that I might set up a small ground blind out of balsam boughs. I know that the tracks were fresh cuz it was snowing on my walk in to the blind and it stopped shortly after I climbed in. Should I call constantly or just wait a minute or two inbetween series? I'm afraid that my movement will be picked out by anything coming in.
