California has grand plans to turn a stretch of abandoned railroad tracks into 300 miles of walking and biking trails, connecting the rolling hills of Marin County with the redwood forests near Eureka in Northern Humboldt.

Reporter Sam Anderson explores how this grand idea has resurfaced the painful and complicated history behind the original railroad tracks that were built more than a century ago.
