From New York to San Francisco, Times Square to the Tenderloin, graffiti artists, young people, radical environmentalists, and the homeless clash with police on city streets in an attempt to take back urban spaces from the developers and 'disneyfiers'. Drawing on more than a decade of first-hand research, this lively account goes inside the worlds of street musicians, homeless punks, militant bicycle activists, high-risk 'BASE jump' parachutists, skateboarders, outlaw radio operators, and hip hop graffiti artists, to explore the day-to-day skirmishes in the struggle over public life and public space.
