Maintained and stayed away from the weird peripheral window dressing of amphetamine and exhaustion, the spectral, luminous vegetation that grows out of the corners of the mind's eye along late-night highways. But the mind had its own ideas, and Kihn's opinion of what I was already thinking of as my "sighting" rattled endlessly through my head in a tight, lopsided orbit. Semiotic ghosts. Fragments of the Mass Dream, whirling past in the wind of my passage. Somehow this feedback-loop aggravated the diet pill, and the speed-vegetation along the road began to assume the colors of infrared satellite images, glowing shreds blown apart in the Toyota's slipstream.

I pulled over, then, and a half-dozen aluminum beer cans winked goodnight as I killed the headlights. I wondered what time it was in London, and tried to imagine Dialta Downes having breakfast in her Hampstead flat, surrounded by streamlined chrome figurines and books on American culture.

Desert nights in that country are enormous; the moon is closer. I watched the moon for a long time and decided that Kihn was right. The main thing was not to worry. All across the continent, daily, people who were more normal than I'd ever aspired to be saw giant birds, Bigfeet, flying oil refineries; they kept Kihn busy and solvent. Why should I be upset by a glimpse of the 1930s pop imagination loose over Bolinas? I decided to go to sleep, with nothing worse to worry about than rattlesnakes and cannibal hippies, safe amid the friendly roadside garbage of my own familiar continuum. In the morning I'd drive down to Nogales and photograph the old brothels, something I'd intended to do for years. The diet pill had given up.

The light woke me, and then the voices. The light came from somewhere behind me and threw shifting shadows inside the car. The voices were calm, indistinct, male and female, engaged in conversation.

My neck was stiff and my eyeballs felt gritty in their sockets. My leg had gone to sleep, pressed against the steering wheel. I fumbled for my glasses in the pocket of my work shirt and finally got them on.
