Bring a small child. No one messes with you if you had a small child with you. Or an Appache Helicopter.
Went to Balt. two years ago to watch them beat up on the Broncos. Sat high up in the End Zone. No trouble at all though. Just don't egg people on or be obnoxious. Sounds obvious, but some people have a hard time understanding why they are getting beer dumped on them after they just insulted an entire section for 2 plus hours.
