The National Orange Show is an annual fair held in San Bernardino each May, on a permanent fairgrounds site in the southern part of the city. Founded in 1911 to celebrate the Inland Empire's citrus industry, it evolved into a general fair with carnival rides, livestock shows, entertainment acts, and the expected orange-themed food and display.
Today the NOS Events Center on the fairgrounds hosts concerts and events throughout the year, making it one of the region's main entertainment venues. The annual fair itself is a good-natured Southern California tradition — nostalgic, family-oriented, and unpretentious. The Orange Show Speedway, a dirt track on the same grounds, runs racing events on weekend nights.
