LOS ANGELES (CBS) — Racers will take over the streets of downtown Los Angeles Saturday — soapbox derby racers, that is.

The Red Bull Soapbox Race returns to downtown Saturday, featuring some of the most whimsical and creative arts and crafts available on four wheels. Teams include the Angry Bird Droppings (based on the popular iPhone/iPad game) from Garden Grove, Team Waynes’ World from Orange County and Lucha Libre of East Los Angeles.
