Suddenly the bay of a hound cut through the gloom. Two small brown dogs with the men, straining at their leashes. He hadn't counted on that. Swiftly he took cover and lined his sights with the blue uniforms. Before they knew even his approximate location he had cut them down, and the dogs also, and raced wildly down the remainder of the hill to the car. "Fare may be calculated from the accompanying charts, and will be collected when your car has taken its place on the Roads," said a little sign near the cockpit. Krenner studied the dashboard for a moment, then jammed in the button marked "Forward," and settled back. The monorail slid forward without a sound, and plunged into a tunnel in the hill. Out the other side, with ever-increasing acceleration it slid in alongside the gleaming silver ribbon, faster and faster. With growing apprehension Krenner watched the speedometer mount, past two hundred, two hundred and twenty, forty, sixty, eighty--at three hundred miles per hour the acceleration force eased, and the car suddenly swerved to the left, into a dark causeway. And then into the brightly lighted plasti-glass tunnel. He was on the Roads! Alongside the outside lane the little car sped, moving on an independent rail, sliding gently past other cars resting on the middle lane. An opening appeared, and Krenner's car slid over another notch, disengaged its rail, and settled to a stop on the central lane of the Road. The speedometer fell to nothing, for the car's motion was no longer independent, but an integral part of the speeding Road itself. Three hundred miles per hour on a constant, nonstop flight across the rolling land. A loudspeaker suddenly piped up in his car. "Welcome to the Roads," it said. "Your fare collector will be with you in a short while. After he has arrived, feel free to leave your car and be at ease on the Road outside. Eating, resting, and sleeping quarters will be found at regular intervals. You are warned, however, not to cross either the barriers to the outside lanes, nor the barriers to the freight-carrying areas front and rear. Pleasant travelling." Krenner chuckled grimly, and settled down in his car, his automatic in his hand. His fare collector would get a surprise. Down the Road a short distance he saw the man approaching, wearing the green uniform of the Roads. And then he stiffened. Three blue uniforms were accompanying him. Opening the car door swiftly, he slipped out onto the soft carpeting of the Road, and raced swiftly away from the approaching men.
