If you went:

1) Were there a lot of Ravens fans there?
-How many, what % would you say?

2) How does this compare to when the Ravens are
-Normally there
-The 2011 championship and 2009 first round

3) How were you treated ther?

On TV, I could not really hear and "O". When the Ravens got their first TD I heard some cheers, not much, but much louder I heard the army chant.
Towards the end of the game as Patriots fans left I then saw a whole bunch and the chant was very very loud.

So to me it seems maybe 5% or 3000 Ravens fans scattered? My guess, what did you see?
