It seems like it's a popular destination for Mexican school kids. There were hundreds of the little critters milling about the place.
At the top of the Sun pyramid, apparently, if you stand at the very centre you can partake in some kind of metaphysical energy being channelled up from the earth. I didn't get a chance because this bunch of American gits were too busy pretending to meditate and drawing psychically inspired pictures. It was nice being up there, anyway.
After a fun afternoon walking around Teotihuacan, we had an alfresco lunch at a nearby restaurant. My most vivid memory of this is how tasty the orange juice I ordered was. Drinks seem to be categorically sweeter in Mexico.
