The first annual Sonora Rodeo was held May 5-6, 1916, at the high school baseball field. It consisted of fourteen events. The 1919 rodeo, as well as several others, was filmed by a Hollywood cameraman. Regardless, the rodeos suffered financially in the years to come. Due to the war effort, a decline in good rodeo stock, and “fake” performers, attendance fell dramatically. Each year, the Sonora Rodeo had a different director, adding to its financial difficulties.
The 1928 rodeo saw the arrival of an investor. Mrs. Jonathan J. Crooks of San Rafael, heiress to the J.J. Case farm equipment fortune, attended the rodeo and, only days later, contacted Martin Liljedahl, purchasing from him the 50-acre racetrack where the rodeos were held.
It was in 1938 that Sonora began the practice of decorating Washington Street prior to the parade and rodeo. In 1941 the rodeo chairman was V.W. “Bill” West. That year marked the end of an era in local rodeo history. A kiddie parade was added, and the “Days of Gold” Parade was led by “Montie Montana.” The final rodeo before World War II was held in 1942.
During World War II, from 1943-1945, no rodeos were held. In the post-World War II years, the rodeo became a part of the 29th District Agricultural Association. In 1946, through the fair’s cooperation, two one-day rodeos were presented. The Eagles Lodge sponsored rodeos for the following two years.
Then, in 1949, the Sonora Rodeo again underwent a change in direction. The annual fair was held May 29 and 30 of that year. The rodeo was directed by the fair board. The “Days of Gold” Parade was sponsored and directed by the Tuolumne County Sheriff’s Posse, which had been formed the previous year. The posse began conducting the Sonora Rodeo in 1950 and, in 1958, the Tuolumne County Sheriff’s Posse received permission to conduct a full-scale rodeo on the traditional Mother’s Day Weekend (the weekend chosen by Mrs. Crooks when she became a benefactor).
This year’s event marks the 67th annual Mother Lode Round-Up and Parade put on by the Tuolumne County Sheriff’s Posse.
