The barren Outback, as I discovered, is a land of ingenious adaptations. In Alice Springs I visited the "School
of the Air," where children in remote areas are taught via two-way radios. I also visited the headquarters of the Royal
Flying Doctor's Service, which provides aerial medical service to Outback residents -- like an ambulance in the air. Another
adaptation is the road train, massive trucks some of which are over 200 feet long. You need at least a mile of open highway to
pass these behemoths.
