As the so called "master of disaster" for S.F. Department of Emergency Management, executive director Mary Ellen Carroll had been preparing for an earthquake. But she got a pandemic, and found a home base in Moscone Center, which has become a place of joy for San Francisco residents getting their vaccines. Carroll gives hosts Peter Hartlaub and Heather Knight a tour of the facility, and then sits down for an interview about preparedness, Anthony Fauci cardboard cutouts and why San Franciscans can be proud of what they've done for each other. Produced by Peter Hartlaub. Music is "The Tide Will Rise" by the Sunset Shipwrecks off their album "Community" and cable car bell-ringing by 8-time champion Byron Cobb.
