Forget Santa Claus! In Puerto Rico, as in much of the Latin world, the Three Kings rule the Christmas season. Puerto Ricans celebrate December 25, but the most important day of the season falls on January 6, El D�a de los Tres Reyes Magos, or Three Kings Day. A typical island tradition calls for children to gather grass and place it in a box at the foot of their beds, so that the camels of the Three Kings will have something to eat when they come to visit. While it is a revered holiday throughout Puerto Rico, nobody does Three Kings Day quite like the small, southern town of Juana Diaz, whose Three Kings tour the island before making the voyage home.
