First-lap ceremonies at the Circuit Of The Americas in Austin, TX with Mario Andretti doing the honors in his 1979 John Players Special F1 car. Various cars from different racing series represented after that.
Video quality is very rough -- sorry! -- as it was shot spur-of-the-moment on a cell phone. I wish I had known how well it picked up the engine notes and had followed Mario through turn one.
The facilities are under constructions (crews appear to be working 7-days a week) but look very nice. There is a quick (rough) glimpse from the flag stand.
