I would take the man's word as you expect him to take your's. All he has to do is move his camera and corn pile 15 yards and everybody will be happy. Offer to take the boy deer hunting, maybe he wants to hunt and dad don't hunt. I have been in situations before where a little compromise goes a long way and cause you to have friendly neighbors instead of enemies. Enemies that border the place you hunt can be a major problem as we have seen on here.
