Best insider tip for RFK Stadium?

RFK Stadium is a venue in Washington DC

From a man who has enjoyed countless United games, my suggestion is this, round up your friends, tailgate hard, hit the fan sections, bounce with the crowds in the rickety bleachers, mosh it up in the halftime drum circle, toss a beer in the air and throw a couple more back, sleep it off sore, then wake with a smile on your face.
