Married couple Michael Morris and David Sweeney started putting on festive light-up tree costumes for a TV-20 "Dance Party" episode seven years ago. They got such a great reaction, they upped the costume details, upped the glitter and heels and upped their holiday spirit — surprising different neighborhoods in San Francisco throughout the holiday season as the Tree Twins. After Heather Knight spent a fun evening in North Beach with the twins, Total SF hosts Knight and Peter Hartlaub join Morris and Sweeney in their home, to talk about costume-making, what San Francisco neighborhoods are the best and worst for a tree visit — and why the city needs spontaneous joy more than ever.
