The car was ordinary enough; it was one of those scaled-down vehicles which burn less fuel and offer less comfort than the so-called standard models. For fuel economy too, its speed had been lowered. But Lockley sent it up the brand-new highway as fast as it would go. Now the highway followed a broad valley with a meadow-like floor. Now it seemed to pick its way between cliffs, and on occasion it ran over a concrete bridge spanning some swiftly flowing stream. At least once it went through a cut which might as well have been a tunnel, and the crackling noise of its motor echoed back from stony walls on either side. He did not see another vehicle for a long way. Deer, he saw twice. Over and over again coveys of small birds rocketed up from beside the road and dived to cover after he had passed. Once he saw movement out of the corner of his eye and looked automatically to see what it was, but saw nothing. Which meant that it was probably a mountain lion, blending perfectly with its background as it watched the car. At the end of five miles he saw a motor truck, empty, trundling away from Boulder Lake and the construction camp toward the outer world. The two vehicles passed, combining to make a momentary roaring noise at their nearest. The truck was not in a hurry. It simply lumbered along with loose objects in its cargo space rattling and bumping loudly. Its driver and his helper plainly knew nothing of untoward events behind them. They'd probably stopped somewhere to have a leisurely morning snack, with the truck waiting for them at the roadside. Lockley went on ten miles more. He begrudged the distances added by curves in the road. He tended to fume when his underpowered car noticeably slowed up on grades, and especially the long ones. He saw a bear halfway up a hillside pause in its exploitation of a berry patch to watch the car go by below it. He saw more deer. Once a smaller animal, probably a coyote, dived into a patch of brushwood and stayed hidden as long as the car remained in sight. More miles of empty highway. And then a long, straight stretch of road, and he suddenly saw vehicles coming around the curve at the end of it. They were not in line, singlelane, as traffic usually is on a curve. Both lanes were filled. The road was blocked by motor-driven traffic heading away from the lake, and not at a steady pace, but in headlong flight. It roared on toward Lockley. Big trucks and little ones; passenger cars in between them; a few motorcyclists catching up from the rear by riding on the road's shoulders. They were closely packed, as if by some freak the lead had been taken by great trucks incapable of the road speed of those behind them, yet with the frantic rearmost cars unable to pass. There was a humming and roaring of motors that filled the air. They plunged toward Lockley's miniature roadster. Truck horns blared.
