Park(ing) Day famously helped people all over the world re-envision the lowly parking spot, encouraging DIY urbanists for one day each fall to transform these spaces in their cities into parks, playgrounds, pop-up cafés – anything other than their intended use. The original idea, dreamed up by San Francisco-based urban design studio Rebar, went on to become a model urban prototype. The city of San Francisco adopted the concept for its “parklet” program. And now officially sanctioned parklets are popping up everywhere, most recently 2,000 miles away in Chicago.
