San Francisco supervisor Myrna Melgar has been dancing in the Mission District's Carnaval festival since the 1980s, and once marched costumed in high heels when she was eight months pregnant. District 7 supervisor Melgar joins Total SF hosts Heather Knight and Peter Hartlaub to give her inside story on Carnaval, and also talk about car-free JFK the Nordstrom valet lot and her commissioned study proving male supervisors talk more than the women. Melgar also takes on the Total SF lightning round, picking her favorite place in S.F. to get a burrito, and which supervisor she'd like to take to Carnaval. 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.
