Just got this email from Lime Rock park:

1. Grand-Am season finales set for Lime Rock Park... As was announced by Grand-Am today, the Rolex Sports Car Series and the Continental Tire Sports Car Challenge series are coming to Lime Rock Park for Grand-Am’s season finale, September 28-29. Skip Barber said, “We have loyal, very knowledgeable fans that we wanted to reward with the very real possibility that all four championships won’t be decided until the last races get the checker here at Lime Rock. Grand-Am racing is almost always very close and competitive, and to have driver and manufacturer titles decided here – maybe on the last lap – well, that makes the weekend all that more exciting, doesn’t it?”
Tickets for the Grand-Am season finale at Lime Rock are not yet available, but we expect to be able to make them available as soon as the complete 2012 Lime Rock schedule is announced.


I think its pretty cool. If you're into that sorta thing
