Happened across this gem of a moment by accident. I was online with a pair of GTP member, one asked if I had done "the ring" in the dark. I set the time to 23:30, time scale to 5 jumped in my F430 and off I went. I think I had the slowest car, so they fell in behind and we just sailed around the track for a few laps. Then one of them said, is it starting to get light? It took almost two laps for it to become light, our tires were shot, but we stayed out to watch the sun come up. A magical moment.
