You've got that right Breechplug. One of my favorite tatics is to hunt one of my box stands on a food plot in the morning. Then about ten o'clock I creep to a ladder in the woods about 100 yards away from the field. I stay there until about three, then move back to the box stand for the late evening.
That makes for a long day though and if I know one of the guys in the club shot a deer in the morning I get itching to head back to camp and join in the fun. So I only manage the all day thing a half dozen times during the season.
