All in all, it was amazing. I think next year I'll go to both the Indy and ALMS races. The sound echoing off the buildings was crazy awesome. The speed is intense. They'd appear out of nowhere doing 150+ and then brake in the blink of an eye for that first corner. Lot of overtaking down at that corner, too.
Some pix. I only had my iphone on me, and the windows of the building are tinted. But at least you can get a sense of the view. We got the end of the major straight and the hairpin.
