Half Time: Yep I was told to sit too - that caught me by surprise. I heard security kicked out a guy that just tripped and cited that he was drunk when it was just an accident. Seems like security is more strict this year?
Championship Banner: Seems oddly out of place. Some around me guessed maybe they didn't have enough to fill in the corners with the ribbon boards so they used that as a placeholder.
Ref Mic: Sounded good at first but then seemed kinda muted.
PA System: Seems like they added speakers to the other side of the stadium and not just on the board? They also seemed to have fixed the sound delay / reverb when showing action on the screen.
Video Board: Is it me or does that screen look way better and brighter than last year??
