This isn't an area where good BBQ is easy to find. I've never found any good BBQ in the WRJ area. How far are you willing to range out from there? The closest really good BBQ in New Hampshire is Goody Coles Smokehouse over in Brentwood, NH.
Brother Rich Decker sells some good 'cue out of a trailer up near Burlington, VT around lunchtime if you're up that way. He is set up on Suzy Wilson drive in the Colchester/Essex Junction area.
Blue Ribbon, in West Newton is very good if you get to the Boston area.
