Hi Roger: I've enjoyed your postings about Chichen Itza as it is my favorite pyramid in Mexico. Here are a couple of unrelated tidbits that I thought might interest you.
When I visited the Chichen Itza pyramid years ago, I noticed that that if I stood in front of the "good " side (not the side that is still in ruins) and clapped my hands, the most curious echo I've ever heard resulted that sounded like "zzzzzing". Even the guide didn't know about the echo effect. Later in the day of my visit I saw a bunch of tourists clapping their hand imitating the guide! Also, I love building sand castles when at the beach, and the Chichen Itza pyramid is one of my favorites things to build as it is fairly easy to do and very erosion stable. Take care, and enjoy your warming temperatures! John
