Thanks! I don't know much, but I do know the area pretty well.
Anyway, a simple test would be to ask Nats fans if they are also O's fan...you'll hear a resounding yes! Now, if you ask O's fans if they are also Nats fans...not so much. It will take two generations of "winning"---along with the team not packing its bags and heading to Minnesota or Texas---before for the Nats are absorbed into the hearts and minds of DC society; a form of enmeshment. As I mentioned other than the Redskins, this town has very little sports fan loyalty.
In comparison, the folks in my native Detroit would bleed for their sports teams. To be honest, except for the crappy weather, horrible economy and lack of quality jobs, I really miss living in the area because each sports season has a feel...an attitude...a passion; and you can embrace your fellow Detroiters in a shared common goal. Moreover, while there are numerous transplants (mostly from Oklahoma and Arkansas) in the North Dallas area...for the most part everyone falls in line behind Cowboy football. While I refused to follow the Bullets and Caps, I didn't mind occasionally following the Mavs and Stars. Go figure!
In a nutshell, DC is one of the worst sports towns anywhere! They are the worst because this city has no heart nor passion for their teams. However, they are also one of the best because I am always getting free tickets to local sports venues where I can wear my Red Wings attire without harrassment...and being a cheap bastard I love free tickets.
If anyone needs more proof here is list of the botton five cities for sports fans...and several fans felt compellted to opine that DC should have been captured on the list. Go figure!
