Zayets- Sunday is a great day to go, it's definitely my favorite at least. The Speed World Challenge GT is an awesome series, and the very last of the whole weekend. Last year it was one of the most exciting races I've ever seen. I don't remember where the Bridgestone seating area is, but turn nine is Bridgestone Turn so i wouldn't be surprised if its near there.
Yellowmr- Those ALMS cars definitely are amazing, Porsche seems to have a very promising package this year with the prototype cars.
S.E.V. - I'll likely be spending most of my time in the SPP areas at turn one and turn six. Good luck with the gear from Canon, let me know how that goes. I think it'd be cool if we could get a photo area full of all POTN shooters at some point.
