After spending my teens in a mid 50s suburb (now considered near downtown), I've always lived in inner city neighborhoods. They are MUCH DENSER than current zoning codes permit. Narrow frontages, separations and streets with garages on back alleys give you lots of density AND neighborhoods people want to live in.
