The next Joshua Tree Clean Team clean-up will be held tomorrow on Alta Loma and Sherwood, just west of Friendly Hills Elementary School. Volunteers can park along Sherwood at 7 a.m. and work for one short hour until 8 a.m. There will be trash bags, grabber sticks and gloves available for the workers’ use. Afterwards, everyone is invited to the Park Rock Café for coffee and conversation.
