The "CMC Carnival" was organized by one of the leather motorcycle clubs, the "California Motorcycle Club", with the help of other gay motorcycle clubs. The members of these gay motorcycle clubs rode mostly Harley Davidson motorcycles and on periodic weekends rode their motorcycles to outings at picnic grounds in the Sierra Nevada. The first gay motorcycle club in the United States was the Satyrs, founded in Los Angeles in 1954. The first gay motorcycle club in San Francisco was the Warlocks, which was founded in 1960, followed by the California Motorcycle Club, also founded in 1960 later in the year. By the mid-1960s, San Francisco's South of Market district had become the center of the gay motorcycle club scene and was home to motorcycle clubs such as the Barbary Coasters (founded in 1966) and the Constantines and the Cheaters (both founded in 1967). Some leather people of the 1960s and 1970s felt that one was not really a leather person but just a poseur unless one owned an actual motorcycle, preferably a Harley Davidson.
