Europe has the nurburgring, we've got Road America. If you are a road racing fan and haven't yet, make the pilgrimage. Also, get yourself on the track on one of the sponsored track days, or at least during touring. The "Drive for Babies" event put on as a fundraiser by the SCCA for March of Dimes every October is a great event. Go to the vintage races in July, the ALMS in August, and get to the NASCAR guys when they are there too.
