I think they all came up to Washington! I've got more than usual out front here: "For two decades, hundreds of sea lions have made their home at San Francisco’s Pier 39. They have provided hours of entertainment to onlookers from all over the world. Recently, however, these entertaining sea mammals have disappeared and no one knows why.
The Marine Mammal Center counted more than 1700 sea lions on October 23rd. On December 29th, only about a dozen were found and these were attempting to climb on docks other than the ones reserved for them."
