When the Orange County Fair started, after World War II, it had been a long time in coming. Los Angeles Times articles as early as the late 1930s talk about the county trying to get the state to use taxes on horse racing — then a much bigger pastime than it is now — to purchase some land and construct a building for a fair.
County board supervisors and Santa Ana Chamber of Commerce members wanted to bring a fair back to the area — the last fair they had was long defunct.
It wasn’t until 1948 that they got their wish. Then, in 1949, the fair took over the old Santa Ana Army Air Base, where it now resides, with the help of $65,000 in state funds to purchase it from the War Assets Administration.
