Huell heads to the “greenest” fair in California. The Marin County Fair has made a huge effort to make a very small footprint on the environment. The carousel and the main stage are both powered by solar. Another stage is powered by a 99% vegetable oil biodiesel generator and the lighting at the entrance to the fair is powered by a wind turbine. There is even an all-electric, solar-powered trackless train to take guests on excursion rides. Even the animal’s straw and manure from the Barnyard is collected and trucked to an organic farm in West Marin after the fair.
