San Francisco Trolley Dances @ Duboce Park (Sat. and Sun.)
It's the hard-earned right of San Franciscans to complain about Muni. But imagine if your daily commute were like a flash mob: Instead of sporadic fights between riders, there are spontaneous, exquisitely choreographed dance pieces. This weekend you can realize that public transit musical, as dance takes over certain routes. For two afternoons, San Francisco Trolley Dance performers occupy Muni stations and perform a diverse and captivating selection that uses open space and city streets. (Free, 11 a.m.) -- Allison Davis
