"We grow up hearing so often that a straight line is the shortest distance between two points that we end up thinking it is also the best way to get there. A river knows better-:it has to do with how it dissipates the energy of its flow most efficiently; and how, in its bends, the sediment deposited soon turns into marshes and swampy islands, harboring all manner of interesting life, imparting charm and character to the whole waterway. I would defy you to find a river on this planet that prefers to run straight, unless it has been taught so by the U.S. Army Corps of Engineers."
