The 19th Hole – a story of Golf and Rail. Back in the 1920s when Tres Pinos was at its height of success, they built Bolado Park. People wanted and needed something to do. George Bolado, a maverick of his time only wanted to make his golf course 17 holes and call his bar the 18th hole so people would feel like they needed to “finish” their game. But his rival in town, Joseph Pinos built a bar first and called it the 19th Hole assuming that golf course would have18 holes. Hence, the golf reference…no matter what Luis Says. Bolado Park, located in Tres Pinos, is home to the San Benito County Fair and San Benito County Saddle Horse Show & Rodeo. The Bolado Park Golf Course is operated by a concessionaire. The park and fair are operated by the 33rd District Agricultural Association. The association is overseen by a seven-member board of directors appointed by the governor.
