Dover is just another town. yes it has the 4 acre zoning rule, but it's not what you are implying anymore than any other town around there.
you want a dig on Dover? look into a guy named William Baker. . . and the Wellesley Hotel that was actually in Needham and existent before the town of Wellesley was incorporated.
PS: dover almost abutts the campas of Wellesley College.
PS: Dover is acessible, friendly and not a 'snob' town. It's a nuevo rich town.
