Apologies for the lack of BMW content, but since we all like cars, I figured people might like this short video. I found it while preparing for my track day.
It's 8mm video taken at a USRRC sports car race taken at Pacific Raceways here in the Seattle area. There are split window Corvettes and a Ferrari GTO among many others. Too bad there's no sound. Interestingly, with the exception of the wall down the front stretch, and some grandstands, the track layout is basically the same today.
