East of El Paso, the scent of the creosote bush blew in the open window, the crescent moon strung between Saturn and Jupiter above. In the morning the wings of Dogface butterflies flew from the grills of semis. Just the Road, and more Road, as the odometer passed 387,000 miles, 35,000 for the year. It seems no place, no time, to be doing what I’m doing. But then beyond Jacumba, across Tecate Divide, I meet Koji under a cold blue sky. As the first day of December warms, we climb the Laguna Mountains in search of the ornamental eggs (like fancy-syped tiny tires) of Mountain Mahogany Hairstreaks—and find them! 28, in all. Then down into the western hem of the Colorado Desert, where a caterpillar of the California Giant Skipper awaited, plump body in the sun, shiny black head dug into the succulent leaf of a Desert Agave. Yes! (see pics. [below])

At home, heavy winds and rains — which we are about to flee, Thea and I, to Hawaii.
