Graffiti artist Chris ‘FREEDOM’ Pape recently visited the Amtrak tunnel under Riverside Park that was affectionately nicknamed after him with a New York Times photographer in tow. He started doing pieces there back in the 1980s, transforming the space into a subterranean art chamber and returned not too long ago to give a tour of the storied spot and to investigate if all the buff rumors were true. Some of them were, but his work still remains.
