Kevin Baker, writing for Harper’s:
Still unsatisfied, New York Central proposed in 1961 to build a three-level bowling alley over Grand Central's Main Concourse, which would have required lowering the ceiling from sixty feet to fifteen and cutting off from view its glorious blue mural of the zodiac. This, too, was stopped. Foiled again, New York Central resorted to plastering the terminal with ads and bombarding travelers with canned Muzak, complete with commercials, over the public address system.
Good lord.
