Gen Admin is good enough. You can go up any grandstands Friday. Saturday, you'd need to sweet talk the gate keeper, but it's easy to do. Sunday, watch race from T1, you'll see start, finish, and jumbotron, last turn in distance, and T2, and the sequence going into the esses, if you position yourself right.
During practices, go around at watch them, particularly out of the esses, the horse shoe carousel around the tower. GA will not disappoint you, it's a good ticket.
Take pics and post here.
