Most general aviation flying in the desert happens in the early morning. The flight schools are busy this morning. This data is coming in from an ADS-B receiver I have mounted on our roof. Being a geek is awesome and aviation is always awesome.
The bigger airplanes along the northern edge of the map are inbound to Sky Harbor, the grey airplanes in the lower right area are parked at Tucson, and all the yellow airplanes are most likely students and other General Aviation aircraft.
