Fairplex, known prior to 1984 as the Los Angeles County Fairgrounds, has been the home of the L.A. County Fair since 1922. It is located in the city of Pomona, California. The L.A. County Fair is now held during the month of September, but the facility is used year-round to host a variety of educational, commercial, and entertainment such as trade and consumer shows, conventions, and sporting events.
