the Backstretch seating is only from the end of the straight to where the pitramp is, it's small and you can't see much, plus it's one of the few seats in the house where you can get pounded with dirt when the guys bend it in during hots and the heats. Each competitor gets two tickets for these grandstands in their entry packet, although it's not enforced very much, it could be so I wouldn't bank on getting a seat unless a driver has given you a ticket out of their packet. My advice, pinch a few pennies from somewhere else in your trip and get a seat where you can watch the action and enjoy the show.
