one more, if you are hanging on the edge of a field go to the other side and see what the deer will see. A few years ago I was on the edge of a cornfield and saw a buck on the other side. I rattled and he came a runnin'. I set down my antlers, and grabbed my bow of the hanger. Slow, but not slow enough. He picked me off, pulled a u-turn and was gone. After checking it out from his point of view I figure out why. The field I was in had a "crown" to it so that when we had a lot of rain, what the ground didn't soak up would run off the field. So even tho I was 20 feet up a tree, I was directly in his line of sight as he was coming up the very, very, very slight slope. So before you hunt it, check out every angle from the deers point of view.
