All three are nice... I'd rank them VT, ME, NH for overall livability. I lived in Mass. for about 30 years, by necessity, not by choice -- my father lived in Vermont. Back then (10-20 years ago, or more) guns were sort of taken for granted -- the only time anyone fretted was when the flatlanders (from NY, CT, MA) came up for deer hunting season, and all the farmers went out and painted "COW" in big letters on the sides of their cows.
All three will probably be ruined as more and more baby-boomer flatlanders retire there.
