The air compacts, and the high heat squeezes the light. The distant ridges look as sharp as cut metal, as if visible through the pinhole of my fist. But this impressive, oppressive temperature that reveals the horizon beyond the usual smog deceives; "good photo days" come at the onset of 100-degree months or when the sky is scrubbed clean by the winter rain afterward. Now approaches the half year of asthma attacks and crud: our ordinary air, a mix of noxious particulates and detritus (soot, really), that collects like a black coat of paint on bookshelves and the carpet and on plants--on everything in Los Angeles County. Shaken from there by a random fault-slip of life, I now live where at least the dust is white and somewhat manageable. It's worse in the Inland Empire and into San Bernardino where the mustard haze wears out lungs like the padded feet of a geriatric bobcat. Out there, smog is the envy of every first-rate illusionist, the way it makes the mountains disappear.
