In April of 2011 Jayne and I flew from Portland, Oregon to Mexico City. It was a business trip for me, but we wanted to explore the city and the area together. It turned out that the machines I was supposed to install were stuck in customs. Therefore it was like a week of vacation, until my boss finally ordered me back. We visited several quarters of Mexico City, did day trips to Teotihuacan and Cholula/Puebla. Later I came back alone, again for business, for 3 weeks and visited more sites on the weekends, like Tula de Allende, Cuicuilco and Xochicalco.
