Coober Pedy
Bicycling in Australia picture - Coober Pedy is a famous opal mining town that actually is in the middle of the desert. The alien appearance of the land made me wonder how people could survive in such a desolate place. The answer: they live underground. The people had used their mine digging machines to create holes in the ground. More than half of the population of 2000 lives underground, comfortably cool in the summer and comfortably warm in the early mornings of winter. Coober Pedys name is derived from aboriginal language, "white people living in holes". Many public services like the library, churches, a camping site, and even my motel, were underground.
