It is the oldest event in Livermore and part of the famous California 6-Pack Rodeo Circuit.
Rodeo participants frequent the event and it is often used as a backdrop or exteriors site in films.
It is always preceded by the Rodeo parade[1] through the Livermore Downtown area on Saturday morning of the rodeo weekend, and has had concerts by Country and Western musicians, including Mark Chesnutt in 2005.
John McGlinchey, who was president of the Livermore Stockman's Protective Association at the time, conceived the idea of holding a fund-raiser in the form of a rodeo to raise the money.
A committee was appointed by McGlinchey to organise the rodeo, which was held the first time on a portion of a local ranch near the intersection of what is now Interstate 580 and Portola Avenue.
