"Im not saying that its easy to race on an oval track, its just that I find it boring to watch. "
Some of them ARE boring to watch, and they just happen to be at the tracks that are the most widely televised--Daytona, Talladega, etc. Some of the drivers don't like driving at those tracks, either.
Generally speaking, the shorter/slower the track, the better the nascar race is as a spectator sport. The races at Bristol or Martinsville are nearly always interesting. I prever this sort of racing over something like F1 because the drivers don't have to avoid each other like they do in open wheel cars--there's contact in nascar, and lots of it.
