Although I’ve been to Mexico several times, I hadn’t yet had the opportunity to visit Chichén Itzá. Named one of the Seven Wonders of the Modern World, this sacred site has long been on my places to visit. On a recent trip to the Riviera Maya, I joined a tour group and journeyed to the Mayan ruins. As I did when I visited Tikal, I was amazed by the geometry and planning of the ancient people; what a civilization the worshipers of the sun god must have been!
