Not really sure, but I wish I could stay on stand for more than four hours. That is tough. I read about all these guys that get their deer between 11a and 2p. That' s not me. Too many ants in the pants as Jimimac says. I think my best attribute if I had to pick one would be determining sounds. I' ve listened to no short of 87,000 squirrels in my day and am getting to the point where I don' t move to look at the sound behind me only to find it' s a 230# 8pt. squirrel. Limiting the movement is obviously one of many key factors I think. I' ve been busted from deer that I turned in the stand and didn' t know they were there - more than 200 yards away.
