There are 3 registered airports south of I-10 in the 320 square miles of the San Simon Valley and all are located near Rodeo.
The Rodeo airport is operated by Rick and Cleo Chamberlain the owners of Chamberlain Aviation who are both CFIs and Rick is an A&P mechanic. They cater to mostly fixed wing traffic but many weight shift students use the Rodeo Airport as a way point on their cross country.
Mystery Well Ranch is a private strip on the sectionals.
Finally, Amigos del Cielo, home of the Sky Gypsies is an airpark dedicated to light sport aircraft.
