The Albuquerque International Balloon Fiesta is a yearly festival of hot air balloons that takes place in Albuquerque, New Mexico, USA during early October. The Balloon Fiesta is a nine-day event, and has over 500 balloons each year. The event is the largest hot air balloon festival in the world.The Balloon Fiesta began in 1972 as the highlight of a 50th birthday celebration for 770 KOB Radio. The Balloon Fiesta grew each year for decades, and today is the largest balloon convention in the world. The number of registered balloons reached a peak of 1,019 in 2000, prompting the Balloon Fiesta Board to limit the number to 750 starting in 2001, citing a desire for "quality over quantity". The limit was changed to 600 in 2009 — citing recent growth in the city and a loss of landing zones. On any given day during the festival, up to 100,000 spectators may be on the launch field where they are provided the rare opportunity to observe inflation and take off procedures at close quarters. Its a truly wonderful spectacle and a great photo opportunity.
