It's a day where people around the world turn parking spaces into mini parks and social gathering spots.
Oraganizers say the purpose of PARK(ing) Day is to call attention to the need for more alternative transportation and urban open space.
Stephen Box of Park(ing) Day LA said it's also to stir dialogue about how public space is allocated. He said there are seven parking spots for every car in Los Angeles.
"When it comes to allocating space, we're also in the most densely populated neighborhood in L.A., and there are no parks in this neighborhood. So we're challenging that kind of inequity," Box said.
Box got up early to set up artificial grass and trees at a metered parking spot.
Rebar, a San Francisco-based art and design studio, started PARK(ing) Day in 2005 by converting a parking space into an art exhibit. The event has grown globally ever since.
