The last thing I would do is leave this hole to find less crowded water, as some suggest. This hole was uncrowded until this *hitbag decided to try and run you off. Call him out and let him know what you think. If he can't take that, too freakin' bad. If he wants to get violent, either let him sit in jail afterward or have your buddy bash him in the head with a rock while he's taking it out on you. Either way, he'll get the picture. Going away will only encourage him to do it again.
