Book excerpt: The Orange County Fair is one of Southern California's most anticipated summer events. From its first year in 1890 with a few livestock exhibits and horse races, the fair evolved into what is now a month-long extravaganza of rides, games and entertainment that still celebrates the importance of local agriculture. Millions of visitors have crowded the grounds over the years to enjoy the spectacle of everything from ostrich races and demolition derbies to its unique Centennial Farm and the time-honored All-Alaskan pig race. Author Chris Epting recounts more than a century of community history and revelry at the OC Fair.
