I'd also recommend any of the D+D meetup groups. (There's a few locally.)
They usually meet once a month or so; the one I frequent is at the Watertown Public Libtrary, but there may be some closer to you. (Go to meetup.com and poke around, see what you find.)
Our Thursday night group (currently playing Pathfinder) always has an open-door policy, if you're interested in checking our group out, assuming Waltham is not too far for you to get to on a weeknight. PM or Email me if you're interested.
Hope that helps, and welcome to the boards!
