Sierra Sonza does some "open air" painting at Plein Air Park, one of four "parks" created in parking spots along Rainier Avenue as part of Park(ing) Day,, which was billed as a "one-day, global event to highlight the need for more urban open space, rethink the way green space can happen, and improve the quality of urban human habitat." SEEDArts and volunteers from the Gateway Project helped organize the event on Sept. 19.
