From mid-September to mid-October it is Tijuana River Action Month. Many organizations, agencies, and public volunteers combine forces to remove trash, tires, and invasive plants from the Tijuana River Valley. I Love a Clean San Diego, Wildcoast, and Surfrider will be sponsoring clean up events. (See their websites under Other Organizations). There will also be fun children’s activities, and opportunities to plant native species at Friendship Park.
