This sounds like a blast!
I don't know what kind of attendance you're expecting / able to handle, but I run/play games with a group that meets in Woonsocket, and I'd imagine at least three of four of us would be interested in coming down - I know I am. Between the lot of us, we play D&D (3.nothing, I run this), All Flesh Must Be Eaten, Shadowrun, and I could try out some Call of Cthulhu, in a pinch. (Keep in mind, I'm far from an experienced Keeper.) We've also got, between the five of us, a decent collection of card and board games, if people are "out of a game", or just looking to do something different in between. I'll put out the word, tonight, and see if anyone wants to try and run something. Regardless, you've probably got a few willing and able players available, if you've got the room.
