Individuals and communities are gathering together today to transform metered parking spaces into temporary Park(ing) public places.  What began as a single art installation by San Francisco design studio, Rebar, has turned into a global movement to bring awareness to the need for public open space especially in underserved urban areas.   The annual event has evolved from its original tree-bench-sod model to include gardening demonstrations, free health clinics, and even live music performances.  Check out instillations from 2009.
