Just a heads up there is a Potomac Yard Metrorail Implementation Work Group meeting on October 10th, 2012. That's Wednesday of next week. The Working Group website is here.
This meeting is to go over the impacts of the alternatives being studied. This is important because one of the alternatives is an elevated track and station that will make our neighborhood start to look like the elevated tracks and stations in Tysons/McLean. If you live in the neighborhood or are considering it, you should take a look at the proposed metro plans. There are three plans under consideration, and the locations vary significantly.
Take a look around the metro site. They have lots of good information.
