We arrived in D.F. yesterday for the journey home. Straight away a taxi driver tried to con us. The taxis in Mexico City are very dangerous, at least for gringos anyway. He made us pay an extra three hundred pesos for the journey and we had to pay him or he would have dumped on the side of the road. All the time he continued to smile as though nothing was wrong. I began to feel very negative about Mexico, or at least about Mexico City. That is until the next morning we walked out onto the zocalo which was a cacophany of different sounds. A piano recital of Rhapsody in Blue was in one corner, while in another there were bouncy castles and a fayre for children. In another corner, Mexicans were protesting about the 'murder' of a politician who was involved in preventing the drug trade. In another corner, huge pictures of Communist Russian thinkers and leaders were hung.
