The other night was a Santa Ana Winds night. Southern Californians know what this means. The hot, dry winds come raging down from the high desert, through the San Bernardino mountain passes. They carry dust and debris and the sage-scented shrapnel of the chaparral. They fuel fires and defrock the palms. They howl with glee as they rattle windows and send trash cans tumbling. They tip over semis and send Jacaranda purple blossoms everywhere.
