Re: Northern Virginia Steeler FANS!!
In Arlington & Alexandria-
Crystal City Sports Pub & Bailey's Bar and Grill (neither "official" Steelers bars, but plenty of black-n-gold fans.)
Southside 815 in Alexandria is a Steelers bar and has some tasty southern-style food to boot. I caught a few games there last season before packing up and moving back to Pittsburgh...it's a small place, but has a great vibe.
Baltimorons. What a bunch of douchenozzles.
