Yes, the most reasonable thing is to call the police. Problem is that sometimes the police shows up after they pick the game up and leave and if you don't want to get close enough to get a plate number, it could be hard to get them. Anyway, I know the officers in the Chatham County Sheriff's office and one of them told me they had people calling about firearms being discharged at night in some area. After patrolling the area with unmarked cars for a couple of nights, they finaly caught someone driving around with a gun in his truck. They couldn't charge him for anything though as he hadn't shot anything when they stopped him, but they told him that if they saw him around there again or if he was even thinking about doing anything illegal, he would go down hard...
