This radio program mostly ignores the large body of water that sits only a short block from our studio. Inexcusable, I know, but it's not too late to make amends. For a start, I spoke to David Helvarg, marine conservationist and author of "The Golden Shore: California's Love Affair with the Sea." We talked about David's own love affair with the sea as well as his earlier career as a war correspondent in Central America. Also, a history of beachgoing, the popularization of surfing, the future of the California coastline and a defense of the SpongeBob lifestyle.
