I don't know if they hold the ren fair anymore (I don't hang out with any of those people anymore - casualty of divorce and all that), but it was out on Long Island at the old Guggenheim estate. I think they're still around, but amazingly, they have no website. (well, they are a medieval re-creation society, so maybe they feel the internet is "not period" but I think, more to the point, is that the main folk who run the group aren't tech savvy.)
