Agreed on Mexico City. It's wonderful. Cortés arrived in Mexico with a few hundred men and allied with locals to overturn the Aztec empire, but natives were always the majority of his alliance. And natives have always been the majority of the ancestors of Mexicans, even today. The pre-Hispanic civilization persists in every aspect of life from street grids to artistic styles. There are still more Mexicans living on canals than Venetians. I was bicycling through the mountains of Milpa Alta one day; Milpa Alta is inside the Federal District of central Mexico City but more rural by virtue of steep mountainsides rising straight up from dense valley development. I came to the town of Milpa Santa Anna where I rode to the charming central square. Narrow old streets are colorful and lively there with some cross streets passing each other on bridges due to the steep hillsides. There was a public notice board in the central plaza where all notices were posted -- ten miles from the denser parts of Mexico City -- in Nahuatl -- the original Aztec tongue -- as well as Spanish. Except there was one notice posted only in Nahuatl. I can't tell you what that one said because I don't speak the language, but it really makes you feel like a foreign traveller in the deep past when public notices are still written in Aztec.
