Playing With Light In A Skate Park

Modern skatepark design can be traced back to Burnside Skatepark, a DIY "barge build" beneath the Burnside Bridge, in Portland, Oregon. Skateboarders used an area populated primarily by the city's "undesirable elements" to create a skatepark, building one section at a time. The process is called "design/build" (D/B), and is a characteristic of nearly all the best skateparks today. The design/build process ensures that adjacent skatepark features are harmonious and rideable, allowing skateboarders to create endless "lines" to ride among the many features. The modern public skatepark is relatively new, made possible by legislation such as California's 1998 law stating that skateboarding is an inherently "Hazardous Recreational Activity" (HRA), and therefore municipalities and their employees may not be held liable for claims of negligence resulting in skateboarders' injuries. Parks are usually for persons 14 or over. The world's largest skatepark is located in Shanghai.
