"Let's make trash extinct! Pitch in for California Coastal Cleanup Day and lend a hand throughout the Golden Gate National Parks and beyond! Cleanup and restoration activities will be happening in San Francisco, Marin, and Pacifica. Together we can keep our parks, neighborhoods, and shorelines clean, safe, and healthy for everyone."
