But in the passing years reports had filtered through the prison walls. New men, coming "up for a visit" had brought tales, gross exaggerations, of the Rolling Roads grown huge, a tremendous system building itself up, crossing hills and valleys in unbroken lines, closed in from weather and hijackers, fast and smooth and endless. Criss-crossing the nation, they had said, in never-slowing belts of passengers and freight livestock. The Great Triangle had been first, from Chicago to St. Louis to Old New York, and back to Chicago. Now every town, every village had its small branch, its entrance to the Rolling Roads, and once a man got on the Roads, they had said, he was safe until he tried to get off. Clearly the memory of the reports filtered through Krenner's mind. The great Central Roads run from Old New York to Chicago, through New Washington and Pittsburgh-- Markson was in Pittsburgh-- Krenner started down through the underbrush, travelling south by the sun, the urgency of his mission spurring him on against the pain of his foot, the difficulty of the terrain over which he travelled. He was too far north. Somewhere to the south he'd find the Roads. And once on the Roads, he'd find a way to get off-- * * * * * He stopped at the brink of the hill and gasped in amazement. They ran across the wide valley like silver ribbons. The late afternoon sunlight reflected gold and pink from the plasti-glass encasement, concealing the rushing line of travel within the covering. Like twin serpents, they lay across the hills, about a mile apart, the Road travelling east, and the Road moving west. They stretched as far as he could see. And he could see the white sign which said, "Merryvale Entrance, Westbound, Three miles." As he tramped, across the field he could hear the hum of the Roads grow loud in his ears. An automatic, machinelike hum, a rhythm of motion. Close to the westbound road he moved back eastward along it, toward the little port which formed the entrance to it. And soon he saw the police 'copter which rested near the entrance, and the uniformed men with their rifles, alert. Three of them. Krenner fingered his weapon easily. It was almost dark; they would not see him easily. He kept a small hill between himself and the police and moved in within gunshot range. He could see the rocket-like car resting on its single rail, waiting for a passenger to enter, to touch the button which would activate the tiny rocket engines and move it forward, ever and ever more swiftly until it reached the acceleration of the Roads, and slid over, and became a part of the Road. Moving carefully, he slipped from rock to rock, closer to the car and the men who guarded it.
