Grand-Am Rolex Series right now, albeit under a severe rain delay, so maybe not right now. NASCAR on Sunday, IIRC. I'm a Rolex fan, especially any of the Camaro teams in the GT division. http://www.grand-am.com/LiveTimingScoring.aspx
That Rolex series race was very slow to start out, because of a ridiculous amount of rain. As the rain abated slowly, the race got faster, but suffered lots of crashes. I still can't stand that DP driver who decided to thread his string through a needle to try to get by a Camaro, sending the Camaro into the wall. NASCAR I completely forgot about. Not sure what happened there.
