For my money, an even more spectacular site than Chichen Itza. Incredible ruins in a bucolic setting. We were there on an overcast day with occasional rain, which just made the site that much more ethereal.
Traditional Vaquería dance performed in the main plaza in Downtown Mérida. The dancers are balancing trays with glasses full of water on their heads. (Sorry...this is before I learned I could zoom while taking videos with my still camera.)
