Solar Training, Dream Cities, Hollywood Interiors

Here's a job that can't go overseas -- solar panel installation. We meet the laborers who are attending a "rooftop university" in Long Beach. Plus, a conversation with Wade Graham about "castles," "slabs" and the shaping of cities, as Los Angeles goes through a transformation; and Anthony Iannacci discusses "Hollywood Interiors" and what makes for uniquely Angeleno style and design.
