I can't watch NASCAR either. Many times I've been offered tickets for Pocono, but I have no interest.
But I can pretty much watch any football game any time, college or pro.
I go to the races when they're up in New Hampshire, but honestly, thats why I perfer the European forms of racing i.e F1, GP2, GP3, then again my job involves working with those forms of racing so that might have something to do with it. I'm definitely a hockey person though.
