With Heather Knight leaving for the New York Times, co-hosts Knight and Peter Hartlaub talk about how they met, their friendship and bond with the Total SF community, then each list three things they learned about San Francisco over a five-year partnership. Also in this episode, Hartlaub and Knight give each other the lightning round — and address "Star Trek IV," doom loops and the future of San Francisco. THANK YOU for listening. Please keep following Total SF - we may have announcements about future collaborations and podcasts. 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.
