With the NFL paying so little to the security if you have a badge that looks halfway close to the real thing, I am sure you can get in. With the massive amounts of passes being given out, I am sure alot of sneak into the Super Bowl each year. I know I got into the Club level at Texans games a few times just because I walked in with a Reliant badge from when I was working at Reliant. The badge had nothing to do with the stadium at all. I just acted like I knew what I was doing and where I was going. Now If I could work my way into a suite....
I did at the summit. I just got there real early and walked in. They caught me ten minutes later because I really did have a ticket and wasn't really trying not to be caught. It can be done.
