It's still some time away but you could always check out Templecon, which will be hosted just outside of Providence this year. My GF and I had a blast last year at both the
40k and Fantasy tournaments run and will be attending again this year and met a lot of great players from the area. Unfortunatly we made the trip from
NH so we didn't stay in touch but I do remember bumping into some chaps who played fantasy around the Somersett,
MA area. Also if you don't mind a drive Gamenight.net is located on the cape and has a good fantasy following. Here are the links to Templecon and Gamenight so you can check them out.
