I was Nascar fan for many years, I put up with the confederate flags and bill hillys as perceived them as left over sentiment from the lost cause. I now observe I was quite incorrect on this, the lost cause is part and parcel of Nascar, inherent to it's very existence. I'm done with Nascar, fans who love to see driver induced crashes and fights.
Much prefer MotoGP, road courses and ability to pass, true world wide participation and venues. Besides motorcycles far more fun than cars!
