It's been 50 years since a massive oil spill fouled area beaches and inspired Earth Day, now a worldwide event. Come to where it all started for a family fun day organized by the Community Environmental Council. Check out the Green Car Show (now featuring e-bikes and e-scooters) where you can test-drive vehicles, a kids' zone, and some 200 booths displaying Earth-friendly products and services. Also find sustainable food trucks, a beer garden, and live music. City shuttles are available and there's free valet parking for bikes.
