http://barbermotorsports.com/park/ This track does ChampCar races as well as a few others. This is also the headquarters of Skip Barber Racing School, which has produced drivers like Juan Pablo Montoya. This place was very close to becoming somewhat of a home to the ill-fated U.S. F1 Team in 2010. It is located in a small town outside of Alabama's largest city, Birmingham. The town is called Leeds, Alabama. I'm sure they may let you spectate the happenings provided you have the cash.
