Bridges and Walls: The Fourth Border

The final episode of DnA’s Bridges and Walls examines the "fourth border,” the Southland’s seashore. Undersea fiber optic cables connect the world, but why is Hermosa Beach a popular landing site for them? What price do we pay for our digital connections? And we'll consider an alternate route for traffic-weary Angeleno commuters: a ferry service between the beach towns.

Host Frances Anderton looks at design and architecture from a Los Angeles perspective.
