For his new wave of bombings, Metesky mainly chose public buildings as targets, bombing several of them multiple times. Bombs were left in phone booths, storage lockers and restrooms in public buildings including Grand Central Terminal (five times), Pennsylvania Station (five times), Radio City Music Hall (three times), the New York Public Library (twice), the Port Authority Bus Terminal (twice) and the RCA Building, as well as in the New York City Subway. Metesky also bombed movie theaters, where he cut into seat upholstery and slipped his explosive devices inside.
