Leave gun. Take Canoli.
I don't own one, but was considering buying the new GoPro drone and Hero5 when they come out in a few days. I have PCD (assuming my car makes it down there in time on the 14th) and M school on 12-16. Would they allow you to use a drone to film some stuff of other people driving? Or is there even time while you are waiting? I'm assuming they'd probably frown on the idea for safety reasons in case it fell onto the track. Or maybe you could just do some fly overs after the day is over just to get some footage of the PC, track and area.
