Man, a lot of hate on NASCAR! Apparently I'm in the minority, but I enjoy the NASCAR Grille. It's BY FAR the best restaraunt/bar on property to watch sports. And they also have some pretty good drink specials on NFL Sundays. On top of that, I also enjoy NASCAR, so I don't mind at all the whole racing theme.
While on "sports," I think with the popularity of both, a UFC or WWE store could be successful.
