The New York Times’ “Rooms” series has closed its final door and takes a look back at a year of rooms. The backstage room of a conductor, the little known bowling alley at the Frick, a tiny room in the Lincoln Tunnel, the series carries all the variety of the great city of New York. Where weren’t they allowed in? The CIA, Rikers Island, Goldman Sachs, the Metropolitan Club, and a place reportedly run by the Mafia.
