How well do we know the public places at the heart of our city? Starting in 2007, Sue Mark and Bruce Douglas of the art team marksearch began a four-year exploration of Oakland’s often-overlooked downtown squares--Jefferson, Lafayette, Madison and Lincoln--and the people who frequent them. 10,000 Steps—A Profile of Four Squares follows the artists, dressed as maintenance workers and pushing a recycling cart, as they gather stories (along with the occasional piece of trash), plant gardens, and encourage connections between the groups using the parks, which are among the oldest in the city. Along the way we meet the women who ran an unofficial “USO” for Chinese-American troops during World War II, the boy who grew up to be a Harlem Globetrotter with the help of his park mentor, the hundreds of tai-chi enthusiasts who materialize each morning, and Tina “Tamale” Ramos who tells of her vanished neighborhood, Oakland’s original barrio. Directed by Matt Dibble and produced by marksearch, 2011.
