Christo Running Fence Reels (1976)

The artists known as Christo and Jeanne-Claude along with a hired crew of enthusiastic local assistants erected a major early work spanning both Sonoma and Marin counties in Northern California. "Running Fence", the culmination of 42 months of collaborative efforts, was 24.5 miles long and 18 feet high, with one end dropping down to the Pacific Ocean.
