It was the kind of pure, undiffused light that can only come from a really hot blue sky, the kind that makes even a concrete highway painful to behold and turns every distant reflective surface into a little glint of flame. Do you know how sometimes on very fine days the sun will shine with a particular intensity that makes the most mundane objects in the landscape glow with an unusual radiance, so that buildings and structures you normally pass without a glance suddenly become arresting, even beautiful? Well, they seem to have that light in Australia nearly all the time.
