Our first stop on the cruise was Progresso, Mexico. We took an excursion tour which included a 2 hour bus ride to the ancient Mayan city of Chichen Itza, located in the Yucatan Peninsula of Mexico. The city, at one time, encompassed an area of approximately 14 square miles. We walked around as much of it as possible in the time allowed but still may have to return someday to complete the tour. These were amazing structures and the workers there are still digging up more every day. These buildings are over 1000 years old. A must see location when visiting the Yucatan Peninsula. Thanks, Harry, for the sink hole picture.
