In celebration of Coastal Cleanup Day on September 21, San Francisco and Oakland are challenging each other in a Battle for the Bay, where we'll see which city can clean more neighborhoods! Are you Team San Francisco or Oakland? If you're on Team San Francisco, be sure to sign up for east side cleanup locations led by Rec and Park, including India Basin Shoreline Park, the Port of San Francisco's Heron's Head Park and more.
