Friday, June 22, 2012 Sometimes you have to dig for it. Sometimes you find Stonehenge where you least expect it. Sometimes a close-up shot of Saturn's rings, taken by the Voyager space probe, shows up in a roadside rock. Sometimes the lizards tell you that you're doing it wrong. Sometimes dust devils. Sometimes you can see wind in the far distance, an hour or more before it gets to you, lifting the desert dust and telling you that it's going to become very hot indeed, but you won't see it unless you put on the special goggles first. Sometimes the air rides up over the tops of mountains that are fifty miles away and makes waves, but nobody's riding. Sometimes the moon.
