““In South Texas I saw three interesting things. The first was a tiny girl, maybe ten years old, driving in a 1965 Cadillac. She wasn't going very fast, because I passed her, but still she was cruising right along, with her head tilted back and her mouth open and her little hands gripping the wheel. Then I saw an old man walking up the median strip pulling a wooden cross behind him. It was mounted on something like a golf cart with two spoked wheels. I slowed down to read the hand-lettered sign on his chest. JACKSONVILLE FLA OR BUST I had never been to Jacksonville but I knew it was the home of the Gator Bowl and I had heard it was a boom town, taking in an entire county or some such thing. It seemed an odd destination for a religious pilgrim. Penance maybe for some terrible sin, or some bargain he had worked out with God, or maybe just a crazed hiker. I waved and called out to him, wishing him luck, but he was intent on his marching and had no time for idle greetings. His step was brisk and I was convinced he wouldn't bust. The third interesting thing was a convoy of stake-bed trucks all piled high with loose watermelons and cantaloupes. I was amazed. I couldn't believe that the bottom ones weren't crushed under all that weight, exploding and spraying hazardous melon juice onto the highway. One of nature's tricks with curved surfaces. Topology! I had never made it that far in mathematics and engineering studies, and I knew now that I never would, just as I knew that I would never be a navy pilot or a Treasury agent. I made a B in Statics but I was failing in Dynamics when I withdrew from the field. The course I liked best was one called Strength of Materials. Everybody else hated it because of all the tables we had to memorize but I loved it, the sheared beam. I had once tried to explain to Dupree how things fell apart from being pulled and compressed and twisted and bent and sheared but he wouldn't listen. Whenever that kind of thing came up, he would always say - boast, the way those people do - that he had no head for figures and couldn't do things with his hands, slyly suggesting the presence of finer qualities.””
