Now they live on a trawler in San Pablo Bay and are sharing that trove with the world. Shipwrecks. Whale migrations. Hippies, fish tales, courtroom battles, and secret CIA vessels. ONCE UPON A BAY explores the natural and human history of one of the most extraordinary bodies of water on earth... and the people fighting to protect it.
