I would try to go, just to "do my part" to make sure there are people there. The worst would be to have as much complaining as we've had and then not represent. Granted, I'm only one man, but I'm fairly large so maybe it would look like more...
That said, my ideal scenario would be to show up 5 minutes before broadcast, have the location be so full they aren't letting anyone in, then go to a bar or tailgate instead.
However, I can see the U totally screwing this up for non-students. Like saying "per policy, lots will only open 6 hours before game time which is after the start of Gameday, so you'll have to use public transportation". That would be a game changer for me. I'm assuming this would be a 2:30 or prime time game as otherwise you'd have thousands of people making the trek right at 11:00 to get to the stadium.
