Really the more disappointing part of the whole COTA experience was this, the race day parking lot chaos. Not certain if other lots experienced this, Lot L/M did. Seemed like a free for all, needed some experienced traffic control in there. Took about two hours just to get from the parking spot to Elroy Road. Friday was 60k fans, Saturday 80k fans - both those days were ok for traffic. Not certain today's attendance (edit - apparently 117k), but they had about the same number of lot attendees so maybe that's telling you (COTA) something....eh hem.
