Coober Pedy, Opal Mining Town
We stayed in Coober Pedy on our way down to Adelaide. Coober Pedy is an opal mining town. It gets very hot (45+C in the summers, 110+F), so many of the houses and hotels are underground. The kids were really excited to do some noodling of their own. They had great luck in the museum noodling pit, but not quite as much luck in the public noodling area.
