Trout asked himself out loud what the people did for amusement, and the driver told him a queer story about a night he spent in West Virginia, in the cab of his truck, near a windowless building which droned monotonously.
     "I'd see folks go in, and I'd see folks come out," he said, "but I couldn't figure out what kind of a machine it was that made the drone. The building was a cheap old frame thing set up on cement blocks, and it was out in the middle of nowhere. Cars came and went, and the folks sure seemed to like whatever was doing the droning," he said.
     So he had a look inside. "It was full of folks on rollerskates," he said. "They just went around and around. Nobody smiled. They just went around and around."
