Tried this once before and had some interest, unfortunately life got in the way and I was unable to make the session happen. That said, I am looking to start a weekly (Sunday afternoons and evenings) 3.5 or 4e game in the Crystal City Shops, with either myself or a brave volunteer as the DM. I have a year and a half of experience DMing a 4e game and experience playing 3.5. All we need are players!
The specific place that I have in mind is right next to the Crystal City Metro stop. It is the large courtyard in front of the Subway/Mind Your Body Oasis, known as "The Landing." I am more than willing to teach newcomers!
