Tell him that he's scaring away the deer by getting there so late. He probably just doesn't know any better.

Yesterday I hada guy walk by my stand three times between 3:30 and 4:19 pm (@ 25 yards, then 12 yards, then 20 yards) I tried getting his attention but he was stomping around too noisily to hear me and he never looked into the trees. I would have certainly given him the 'short' course on finding a spot a tad bit before the last hour. [:@]
