Transit lover and poet Mc "Mack" Allen met Total SF hosts Peter Hartlaub and Heather Knight on Total Muni 2018, when he was the first civilian to find them during their successful attempt to ride every Muni line in one day. He's since become a Muni operator, and we invited him back on the podcast to answer "Ask a Muni driver" questions from listeners — including his favorite views, the strangest things he's seen as a driver and what he thinks of the Lunchables ad-wrap on several Muni coaches right now. We also share our "Lunchabus" poetry and Mack reads a new Muni poem. 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.
