Further down the Stuart is the opal town of Coober Pedy where, to escape the heat of summer like all sensible desert creatures, the humans live underground. Only the vents indicate their presence. In theory. Actually mullock heaps, rusted machinery, take-away shops, signs to attract tourists and a convoluted street system are also very much in evidence.
Late this afternoon we drove out to the Breakaways - unexpectedly beautiful and the flat, flat horizon a reminder that this land is big. And even in this distant place there is room for political graffiti.
