The Washington DC area is the current front-runner to be the new home for the Montreal Expos. There are two competing proposals for where the team should play: one group wants to build a stadium in DC proper and the other wants one in Northern Virgina, out in Loudoun county beyond Dulles.
On Friday the head of the DC city council finance committee, Jack Evans, showed his teeth by threatening to pass legislation barring a Northern Virginia team from playing in RFK stadium while the Loudoun stadium was built. This is no mean threat, since a new stadium in either location couldn't be built until 2007 or (probably) 2008 at the earliest so the Expos will be playing in RFK for two or three years regardless.
I say good on him. If I am going to have to drive 40 or so miles to see a baseball game I may as well go to Camden Yards. I'd much rather be able to walk to the metro and take public transportation to the game.
