On a crisp early autumn afternoon in Detroit, some friends and
I went walking in search of a different sort of public art. Armed with
more cameras than people and one football, six of us clambered down
into the abandoned railway known as the Dequindre Cut. While it once
served to bring people and goods to and from the city, the corridor
is now overgrown with trees and has become a grand outdoor studio for
graffiti artists and sculptors.
