Well, 20,000 of us were at the DC United game, and 20,000 others at the Wiz game...tomorrow should be a *little* better. Other local sports teams siphon off a lot of the folks who attend live sports events writ large, particularly when the other teams aren't sewer dwellers. That said, a lot of people (myself included) will be fitting in the Nats this weekend (in between PLAYOFF HOCKEY GAMES!!!).
I love my Nats, and I spend a great deal of time and money attending Nats games throughout the year, but I doubt that I am alone among Washington sports fans in having my energies a bit spread thin at the moment (not a bad problem to have, considering the alternative).
Baltimore filled OPACY for a decade because of a) a good team; b), Cal;, and c), there was nothing else new in town other than the latest Sparrows Point layoffs. The "wow" factor of a new baseball stadium is much lower in WDC.
