I had SRO only tickets for a 2005 game against the Saints.
I got there early and got myself situated in the 'front row' of SRO on the lower level where the only people in front of me were sitting in seats.
Let me tell you, it is still VERY annoying. Everytime the crowd stood up I couldn't see a thing. It sucked.
For the second half I went to the upper level of the stadium. That was better but they didn't let us lean against the railings. There was a yellow line drawn that could not be crossed and was enforced by security guards. (according to another poster, this may have changed)
I would not do it again, and that was for a game against a weak NFC opponent. For the games like the Colts, the crowd will stand up MUCH more often and you will see NOTHING.
