My family lives in Barnard. Good elementary school that moves into the Woodstock district for middle and high school, fast ec fiber internet, not terribly far from Killington or the Upper Valley. We have local family here that are black and biracial and in-laws/friends from Haiti that are here often. Demographics are heavily white in the area, and the whole state, but attitudes appear to be mostly welcoming. I suspect you'll experience less overt racism from actual bigots and more accidental stereotyping from people who are well intentioned but inexperienced with diversity. To my knowledge my black family members in town haven't had any bad experiences, and they aren't the only non-white people in town by any means.
