On the 3rd Saturday in April in a whimsical tribute to Tulare County’s rough-and-tumble Gold Rush-era pioneer days, enthusiasts exuberantly celebrate with the Jackass Mail Run – an annual delivery of specially-stamped mail delivered from Porterville to Springville by mule-drawn wagon. The Wagonmaster is accompanied by folks on horseback from all over the Western United States, drawn by the opportunity to participate in this unique nostalgic event. The Run starts in downtown Porterville in the morning and usually arrives at the Springville Post Office around 4:00pm., if the mail wagon isn’t waylaid by bandits!
