A good place to go if you can get tickets that has great airflow is the field bleachers, right underneath the Beerpen area(right above the Mercedes Benz picnic area). Not many rows, in the shade, bathroom right there and a concession stand right there. You are always in the shade, but get the breeze from the panels. Now some of these can be somewhat obstructed (a pole or two), but they have tv monitors in this entire section to see if by chance you have a bad view.. Cushon and Nelson do their show off of this area, but they are way off to the side Again. these may be hard to get sometimes, so grab em while you can. I like them a lot. I agree it can get sweltering in there at times.. I try to avoid Terrace reserved at all costs (the warm, humid air just pools up there and the glass doesnt help). Terrace box are better and only a few bucks more (because their near tunnels = more airflow)
