Man?! A lot of illegal acts occurring in one area! I don't know about IN, but here in MS, Road hunting, really just having a gun out of it's case loaded in a vehicle is flat out illegal. Also, drinking alcohol while hunting or in possession of a gun wouldn't go too well with a game warden or the county's sheriff dept. either. I'd go ahead and call the game warden or sheriff dept. and get a report started on both the trespassers and road hunter. Then when you catch them in the act, just give law enforcement a call and hope they catch them to give them a hefty fine!
