Brooklyn-based photographer Chris Arnade set out to East New York, the Bronx, and Bushwick looking to photograph pigeon-keepers, and instead found another fascinating subculture: bike clubs. Arnade compared them to motorcycle clubs, with members taking on positions like president and secretary, wearing club vests, and even establishing clubhouses. If you want to see more of his incredible work, check out his show Pigeons and Portraits, whichopens this Friday at Urban Folk Art Studios on Smith Street. All proceeds will go to charities in the neighborhoods where Arnade has taken these photos.
