Hey blue,
It sound like that perhaps you or your dad should call the game warden (if you feel confident about your own law abiding-ness--maybe just say that it would b a good place for him (warden) to patrol once in a while. Chances are if they(road hunter) just see him there they might move to a different road. good luck
