East Coast Skate and Snow is nice. It's also about and hour or so out of Boston. Anything actually in Boston? New to the city myself. Looking for some places to hit up.
Its not huge but in Westford, MA theres a shop called RJ Bradleys and they have some sector 9 completes Talk to Paul there he could probably order a deck if someone wanted it to come in. They're a ski and snowboard and bike shop too. Link
