Growing up, nothing was more fun on the beach than building a castle. I did reach a point, however, where I realized that they were all the same and doomed to be reclaimed by the sea. It appears, though, that some people were not daunted by this futility and, much like Calvin and his snowmen, have displayed amazing creativity and ingenuity in sand sculpture. Exhibits A and B represent the destruction of my childhood compromise with myself that nothing substantial had ever been made from sand on a beach. I would be sad and disillusioned, but these are so cool…well, I can't be sad.
