I shot a 90-mile road race outside of Ely, NV not long ago. My AC and I had to hike up a mountain at 4am to get our camera in position. We were up there for about 12 hours, shooting cars racing at 180mph past us with a RED.

Whip-pans at 180mph with a fully-loaded RED and an AC pulling focus is a tricky thing. We nailed nearly every one of the 100+ cars that passed us.
