Dixon is a city in northern Solano County, California, United States, located 23 miles (37 km) from the state capital, Sacramento. The population was 16,103 at the 2000 census. Other nearby cities include Vacaville, Winters and Davis. The city was originally intended to be named "Dicksonville" after local citizen Thomas Dickson, who had donated some of his land to create a railroad depot. The first rail shipment of merchandise from San Francisco arrived in 1872 mistakenly addressed to “Dixon,” and the new spelling has been used since, mainly out of simplicity. Dixon is also home to the May Fair, the longest running annual fair in the state of California. It is held at the Dixon Fairgrounds in May, with the four day event ending each year on Mother's Day. Dixon is also the home of the Gymboree Corporation's only Distribution Center, servicing all stores and customers around the world.
