Hey man, glad to see that you'd like to get started.
Your best bet would be our group up at Harford Community College. We're very beginner friendly even though some of us have been training for years.
As for other locations, I know of a few traceurs in the Towson area that are very skilled, and further down south I've trained with the Anne Arundel Community College crew, and from what I hear they train twice a week now.
Try checking the mid-atlantic board, it gets a little more traffic as it covers the DC/Virginia hotspots as well, if you don't mind the commute that is.
But I hope to see you at a HCC training session, we'd love to have you!
