I'll watch the road races. Pick up a Race Tech or Racecar Engineering magazine and you'll probably be a lot more interested. Plus, I like listening to Chad Knauss. That guy pretty much knows everything there is to learn about NASCAR racing.
I've been to a CART (yes when it was still called CART) oval race and it wasn't exciting... I was falling asleep through most of the race. It didn't help I had to wake up early, but I didn't enjoy it at all. But everytime I've been to an ALMS race (twice at Long Beach) I've always been excited; mainly because of the variety of cars, sounds, etc.
A NASCAR road race is more exciting than ANY F1 race. I was asleep for a good 20 minutes watching that crap they call racing (German GP)
