Back from the D.F.

Had a wonderful, but exhausting trip to Mexico City. I've been there more than two dozen times, I'd guess. Many of these visits with a group of undergraduate students. I've seen the sights there repeatedly, and I never get tired of them. One of the places I always take the undergrads is the site of the famous pyramids of Teotihuacan. They are so impressive that every new visit to them is just as breathtaking as the last. And there's generally always a little something new to make each visit unique. This time, there was this:


A bit of the modern along with a bit of the pre-Columbian classic. One of my students was on the top of the Pyramid of the Sun when this balloon passed over.
