I was certified national chief corner worker, working captain of turn eleven at Road Atlanta for a formula car race, I don't recall what class. A spectator dropped his beer off the bridge, crossing the track there, nearly into Gordon Johncock's cockpit. Distracted, he spun out and we commiserated. If I had had a gun just then ...!
That was my last spectator race. I went on to race chairman and organizer before retiring from club racing. You might look into the state's gun/alcohol prohibitions. Alcohol fuels GP racing, an invisible fire.
