I cannot watch a NASCAR race. However, I do enjoy ALMS and the british road racing series. Watched one last week that had Cobras and Ferraris from the 70's in it. That was great.
This is why I watch NHRA. Besides being the WORLDS fastest motorsport, it has the market cornered. I also enjoy F1 and Grand-Am. Bring back Can-Am.
But seriously, road racing is where it's at.
