Then I looked behind me and saw the city. The books on Thirties design were in the trunk; one of them contained sketches of an idealized city that drew on Metropolis and Things to Come, but squared everything, soaring up through an architect's perfect clouds to zeppelin docks and mad neon spires. That city was a scale model of the one that rose behind me. Spire stood on spire in gleaming ziggurat steps that climbed to a central golden temple tower ringed with the crazy radiator flanges of the Mongo gas stations. You could hide the Empire State Building in the smallest of those towers. Roads of crystal soared between the spires, crossed and recrossed by smooth silvershapes like beads of running mercury. The air was thick with ships: giant wing-liners, little darting silver things (sometimes one of the quicksilver shapes from the sky bridges rose gracefully into the air and flew up to join the dance), mile-long blimps, hovering dragonfly things that were gyrocopters...

I closed my eyes tight and swung around in the seat. When I opened them, I willed myself to see the mileage meter, the pale road dust on the black plastic dashboard, the overflowing ashtray.

"Amphetamine psychosis," I said. I opened my eyes. The dash was still there, the dust, the crushed filtertips. Very carefully, without moving my head, I turned the headlights on.

And saw them. They were blond. They were standing beside their car, an aluminum avocado with a central shark-fin rudder jutting up from its spine and smooth black tires like a child's toy. He had his arm around her waist and was gesturing toward the city. They were both in white: loose clothing, bare legs, spotless white sun shoes. Neither of them seemed aware of the beams of my headlights. He was saying something wise and strong, and she was nodding, and suddenly I was frightened, frightened in an entirely different way. Sanity had ceased to be an issue; I knew, somehow, that the city behind me was Tucson a dream Tucson thrown up out of the collective yearning of an era. That it was real, entirely real. But the couple in front of me lived in it, and they frightened me.
