The blubbery sea lions at Pier 39, one of San Francisco's smelliest and most famous tourist attractions, are gone. During the last week of November, they left the wooden docks on which they've spent the last 20 years and no one knows if they'll be coming back. "We have no idea where they moved on to or why," said Shelbi Stoudt, who manages a team that helps stranded animals in the San Francisco Bay from the Marine Mammal Center in Sausalito, California.
