The Annual Mendocino County Fair and Apple Show started in 1924. In Mendocino County’s historic and picturesque Anderson Valley, it has remained an old-time harvest festival. This, in the face of a flourishing wine industry and greatly increased tourist traffic, is a cause for celebration. Once a year, Anderson Valley’s biggest metropolis (the sign says “Boonville Pop. 715”), opens the fairground gates to crowds of local folks along with multitudes from out-of-county.
