College Gameday is coming to Philadelphia this week. I live close to the city and I'm always interested when something unusual comes around (for example, the pope).

I've never watched an episode and I haven't watched more than an hour of college football all year.

I am hell bent on going, with a sign and getting on TV.

Do any of you have any protips on what to expect?

For example:
restrictions on signs
reserved / restricted area behind the set
how early should I arrive
how many people should i expect
must i dress in a team's gear (I have plenty of irish costume shit so 'go ND' i guess)

Thanks.
