Last year was the only time I've been, and if I remember correctly, the infield ticket is significantly cheaper than a grandstand seat. I'm thinking my infield ticket was 15, and the seats were 30+? I'm sure someone will correct me if I'm wrong, but that's what I'm remembering.

Watching from down there is okay. It's awesome when they come by you, but it's a bummer when you see a position has changed and you're not sure what happened. I walked around to check out the different views, so that was cool, but being a mile track it obviously takes a bit longer. I'd say stick with buying a seat in the stands, wish I would've last year.
