My husband and I sat in row H of this section, we had the aisle seats. We paid top dollar for these seats and it was well worth it. (Saw the Steelers take on the Seahawks for the 2011 home opener). We purchased our tickets thru Tickets Now which I believe it a subsidiary of Ticketmaster.
The first thing that you recognize when you get to your seats is how yellow this stadium is. Looking to our right, we had a great view of the Pittsburgh skyline and the always beautiful Ohio River. The jumbotron was also to our right and you don't ever want to be in the far endzone because there is only one jumbotron in this stadiums, one of it's few shortcomings. It's neat when the Steelers enter the Red Zone and the two ketchup bottles pour ketchup onto the jumbotron. (Not real ketchup).

The audio presentation is spectacular and the sight lines were great. Our seats were also behind the Steelers bench. If you're looking at tickets for section 537, purchase with confidence.
