The Los Angeles River runs for 80 kilometers through the sprawling city of Los Angeles. For much of the route, however, it's a concrete drainage channel that is dry in summer. Like many other urban waterways, the river is being restored, and volunteers have been doing an annual cleanup. Mike O'Sullivan asked why they are helping.
