The number of parks throughout Philadelphia increases dramatically each year on the third Friday in September, when activists, artists, architects, and other citizens transform metered parking spaces into temporary public parks. Known as PARKing) Day, this annual event re-imagines the possibilities of 140 square feet of public space. The event celebrates parks and other public spaces in cities across the country (and worldwide) and raises awareness of the need for more pedestrian-friendly spaces in our urban areas.
