Set sail from Oakland's Jack London Square for a two-hour San Francisco Bay history cruise on The USS Potomac, Franklin Roosevelt's presidential yacht, which has been restored to its former glory. Begin with a short video that details the history of the ship and how FDR lived from 1936 until his death in 1945. After his death, the Potomac began a long and ignominious decline from her former role in world affairs. After many adventures and many owners, including Elvis Presley, she was used as a front for drug smugglers, but was seized by authorities in 1980. While impounded at Treasure Island, it sank, was raised, and nearly scrapped until the Port of Oakland came to the rescue. Five million dollars, hundreds of volunteer hours and 12 years later, the ship was restored and opened to the public and is now a National Historic Landmark. After the cruise, spend free time on the waterfront in Jack London Square. Register by May 21; call for availability after that date.
