No Bull – They’re Back! The Fair’s Opening Day Cattle Drive, where real-life cowboys and cowgirls guide a mighty herd of steers through Downtown Pleasanton returns for an encore. The event will start at Del Valle Avenue and head on to Main Street at approximately 10:30AM on Friday, June 15. Once again, select downtown restaurants and retailers will be giving away free Fair tickets while supplies last and the Museum on Main will provide fun activities for kids. Wild West Weekend festivities will continue at the Fair through Sunday.
