There's also Sullivan County, NY (the Jewish Alps) which has a significant Jewish population, at least during the summer months. I haven't checked the map, but I imagine they're currently part of c_woodstock, which has purely Ulster County baronies. (The Woodstock Festival locale was actually in the town of Bethel, Sullivan County, not near Woodstock, Ulster County; the anniversary concert was in Ulster County, I think Saugherties but I'd have to check.)
