Quentin Kopp is a former San Francisco supervisor, state senator and judge — but he's known to local journalists as the most prolific angry letter-writer. in the city Total SF co-hosts Peter Hartlaub and Heather Knight visit the self-professed "curmudgeon" to talk about his life, his letter-writing process, what he really thinks of them ... and to wish him a happy 93rd birthday! After making peace, with no apologies, Kopp lets us know his advice for living a long and active life. (It involves more letters to The Chronicle.)

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.
