The whole Baltimore/D.C. or DMV geographic regions when it came to sports teams in both cities or one particular city, was a bit strange and peculiar for the longest time because it seemed, at times, like both cities "shared" or from an outsider's perspective, their was this comorbidity as it related to region's NBA and NHL teams. For decades, the old Bullets either played in D.C. or Baltimore or both cities had some arrangement where Bullets played home games in both D.C. or Baltimore until the late 1990's when D.C. finally built an arena in Chinatown region for both Caps and Wizards around 1998-99. Both Wizards/Bullets and Caps occasionally played home games at the Capital Center until the late 90's so one was never totally sure who's teams they really were. Just recently, Northern Virginia rejected a proposal to build a near-billion dollar arena for the Caps/Wizards in IIRC, around Arlington, a D.C. suburb.
