Is there any detailed information or a documentary as to why USHGA moved to Colorado?
It says here:
http://www.ushpa.aero/aboutus.asp
The USHPA is private, voluntary membership, 501(c)(3) non-profit organization, incorporated as a California corporation but doing business in Colorado.
The USHPA began as the Southern California Hang Gliding Association in 1971 and shortly afterwards, on December 18, 1973, became the United States Hang Gliding Association (USHGA), headquarted in southern California. It was incorporated in March of 1974. In 1989, the Association was moved from Southern California to its present home in Colorado Springs, CO and in 2006, became the United States Hang Gliding and Paragliding Association (USHPA).
