True, though metro Denver/Boulder isn’t cheap at all…sure, areas that are commuting to NYC/Boston may be more $$, but not sure more rural CT (quiet corner), western MA/NH/VT are much different in terms of COL. That said 40K (vs. 30K) is more like day schools in more far-flung areas in NE.
very minor point all around and not very important:) interesting topic though
