From previous experience at RFK, and from watching the DC vs LA Game this is what I see:
1. They allow 1-2 supporters to organize flags / tifo / choreos on the pitch during the game!!! These dudes are running around getting the set-ups ready.
2. They allow the SG's a heck of alot more time to set-up their rail banners. Last time, we were stopped by some guy in a suit named "Tyler" with 4-5 cops with him for approx 10mins before we could bring "The Fortress" banner inside.
3. They allow the supporters to ignite their own smoke bombs!! (I believe this is done by the dudes who also set-up the flags on the pitch)
4. They have given the supporters full control of their ticket seating in their area! That's right they don't have to deal with scalper seats in the South end.
I can see why RFK is "Home of the 12th man" We should be jealous... anything more to add DC supporters?
