Filmed October 20, 2009. The animals began leaving in droves November 27, 2009, almost as if someone had issued an order. San Francisco's Sea Lions could be found sun bathing, barking and up to their old antics at the marina's K-dock. They "hauled out" on PIER 39's K-Dock shortly after the 1989 Loma Prieta earthquake. The boisterous barking pinnipeds started arriving in droves, taking over the docks in January 1990. And visitors to Pier 39 had enjoyed their antics ever since. They have since returned.
