This Valentine's Day is the 50th anniversary of Ruth Asawa's most community-minded work, her San Francisco Fountain, which was conceived with baker's dough and made with contributions from more than a hundred locals ages 3 to 90. Asawa's grandson Henry Weverka joins Total SF hosts Peter Hartlaub, Heather Knight and Tony Bravo to talk about Ruth Asawa's legacy, growing interest in her work, the Apple Store controversy and the history and wonderful details of the fountain. More information about Asawa and her work at www.ruthasawa.com. 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.
