It was told that, on any given day, locals and tourists walking along the sandy beach at Condado, San Juan will find the little boy and his sand castle. Each afternoon he would first build a small dam to keep out the waves. Then he would build a sand castle, with towers and moats, keeps and stairs. Each day he will find a new technique, or refine a feature that he created the day before. Each night the castle is washed away. Each day it is rebuilt. The joy is in the doing, in the building.
