Saturday is the 10th Annual Clean-up Event at Giant Rock, the world’s largest free-standing boulder. Volunteers will gather at Giant Rock in Landers and work from 9 to noon. Trash bags, bottled water and a free lunch donated by the Rib Company will be provided. Each volunteer will also receive a raffle ticket for prizes, including camping gear, tools, and toys, all donated by the Woodman family. For more information or directions, call Dan at 714-322-5937.
