John Wayne Airport (IATA: SNA, ICAO: KSNA, FAA LID: SNA) is an international airport in Orange County, California, United States, with its mailing address in the city of Santa Ana, hence the IATA airport code.
 The entrance to the airport is off MacArthur Blvd in Irvine, the city that borders the airport on the north and east.
 Newport Beach and Costa Mesa form the southern and western boundaries along with a small unincorporated area along the Corona del Mar (73) Freeway.
 Santa Ana is just north, not actually touching the airport.
 Originally named Orange County Airport, the county Board of Supervisors renamed it in 1979 to honor actor John Wayne, who lived in neighboring Newport Beach and died that year.
Air California, later renamed AirCal, was founded by William E. Myers and Bill Perrera and began as an intrastate airline operating solely within California.
 Following the federal Airline Deregulation Act in 1978, it expanded to several destinations in neighboring states, and in the 1980s was flying to Chicago (ORD), Seattle (SEA), Anchorage (ANC), and Vancouver, B.C. (YVR) in addition to its California routes as well as service to other destinations in the western U.S.
 It was founded by a partnership of Orange County businessmen and its initial route when scheduled passenger operations were commenced on January 16, 1967, was nonstop between Orange County Airport (SNA) and San Francisco International Airport (SFO), a previously unserved route, using two Lockheed L-188 Electra turboprops with five daily round trip flights.
 Air California was headquartered in Newport Beach, California.
 The airline's "home" airport was Orange County Airport, now known as John Wayne Airport.
 The airline was renamed AirCal in 1981 and was merged into American Airlines in 1987.
The Orange County Fair is an annual fair held in the town of Wallkill, New York.
 The fair began when farmers of Orange County organized an agricultural society to help promote a county fair.
 In 1808 they tried to organize the fair but it did not generate enough local interest.
 The society tried again in 1818 and held the fair until 1825.
 It took another sixteen years before county leaders met at the Old Stone Courthouse in Goshen, New York on September 11, 1841 and formed the Orange County Agricultural Society.
 That meeting was the birth of the Orange County Fair and the first fair was held on November 17, 1841 in Goshen.
