I just got word that they might be moving the gameday set from the PMAC to the parade grounds because they are expecting so many people. I will check on it futher.
I just drove by around noon and they still had everything set up. I'm not saying you're wrong, but right now they got all kinds of Gameday trucks and busses by the PMAC with no destruction of the set or anything else. They had the cameras set up too.
I think the shot from the PMAC ramp looking at the stadium is too nice to move. They are there for TV ratings, not spectator enjoyment.
