Look, this stuff is nonsense. And I hope they stay out of my neck of the woods. The deer need little incentive to go nocturnal as it is. This is wildlife harassment, pure and simple. But I bet they "hunt" the deer behind fenced enclosures. Only exists to sell more crap.
They want to have a contest, give them something to hunt that would be more useful. How about rodents in a feed mill with slingshots? :D Sounds like something more entertaining, and less rehearsed. But then, I suppose the anti's would say the rodents were taken inhumanely. The point is you can't win with hunting contests because hunting is not a contest.
