The New Sport: Urban Exploring

Taking photos to document their exploits, they slink through steam tunnels and drainpipes, climb idle construction cranes, even descend into abandoned missile silos. Or, like the loose-knit Urban Exploration League in Detroit, they prowl forsaken buildings. Then they post their discoveries online, in narratives so packed with drama that an illicit crawl through a sewer comes off like an expedition to the North Pole... There's an online discussion group devoted to exploring steam tunnels under college campuses, including UCLA. There's even a magazine, Infiltration, published three times a year in Toronto and claiming a circulation of about 2,000. The editor, who identifies himself only as Ninjalicious, says the movement has grown to include several thousand enthusiasts across the United States, Western Europe, Canada, Russia, Australia and Japan."
