Section 453 is a neat section. There were upwards of 25 rows of seats, rows 1 through 10 will probably suit you the best. A lot of the seats are white because the Colts Horse Shoe design is painted into this section. You'll only notice it if the stadium is empty and you have a different perspective elsewhere in the stadium. Here, you'll be directly above the uprights but don't worry, it won't bother your view at all. Behind this section is the North window that opens up when the weather is nice. It lets in a lot of breezes and fresh air, you'll enjoy it. Both the window and the roof will more than likely be open only in for home games in September and October when the weather is nice.
Quickest and most efficient way to get here is to enter through the Lucas Oil Gate on the north side of the stadium and take the escalator to the loge level. Section 453 will be right near where you exit the escalator, you can't miss it. Slim chance that you won't enjoy your seats in this section, the fans were great up there.
