I agree that the anti-hunters would not shoot wildly into the woods. I don't see them using guns for anything. If that was really their agenda, they would have just honked the horn and blasted the radio. That's much cheaper than using ammo...not to give em' any ideas.
It was just some dangerous road hunters and I think we should all do our part to report it when we see it or hear it.
Sorry for the bad luck. I've called off a couple hunts because of similar circumstances.
