After reading the responses to your question, I have concluded, yet again, that nobody in their right mind drives in or anywhere near Mexico City.
Too many other ways to spend one's life.
I know a couple here in Patzcuaro who have lived in Mexico almost 15 years. They have never set foot in Mexico City. It can be done. Color them sharp. From Tzurumutaro, Michoacan, "The Village of the Darned." _______________________________________
