coming into town soon and was wondering if this is a spot to go and check out one day.. are there any other tracks around where any sports car racing occurs? do many exotic sports cars hang out at the park ever?
I would check out their calendar and see if there's an event during the time you'll be there: http://millermotorsportspark.com/calendar/#/month/2009-7-1/all,all/ It is definitely a beautiful facility and I think it's worth checking out, especially if there's a big race going on. You can always do some karting laps and check out the museum or maybe get a tour. Exotics don't necessarily hang out unless you're there for a Porsche open track day or big event (at the ALMS events I've seen a Veyron, R8, Enzo, SLR, F40, Lambos, etc.).
I've only been to one race there so far, but it was a great place. The museum is very cool, especially if you are into Ford Racing. I plan on going to many more races here.
I've done a Porsche Club lapping days event there. It was an absolute blast! I highly recommend going out whenever you have the chance.
