How did the sea lions get to Pier 39? With the pinnipeds dominating the voting for the Official Animal of San Francisco, Total SF hosts Peter Hartlaub and Heather Knight sat down with Pier 39 harbormaster Sheila Chandor and former CEO Taylor Safford to learn about the history of Pier 39's famous marine residents. Chandor and Safford also talk about Pier 39's beginnings as a much-derided tourism center, and why a larger number of locals have been enjoying the waterfront attraction. Produced by Peter Hartlaub. Music from the Sunset Shipwrecks off their album "Community," Castro Theatre organist David Hegarty and cable car bell-ringing by 8-time champion Byron Cobb. Follow Total SF adventures at www.sfchronicle.com/totalsf  Learn more about your ad choices.
