I spent last Sunday night at Alejandro's house, and I woke up at around 7:30 A.M., just before sunrise, on Monday morning. The sky looked clear, so I climbed to the roof. There I had a great view. The volcanoes Iztaccíhuatl (left) and Popocatépetl were silhouetted against a dramatic pre-dawn sky. Also notice the airplane taking off from Mexico City International Airport.
