Mexico City has an interesting history, and many rather ancient ruins, it also has way too many people and traffic for my taste. I really liked Acapulco, and hated leaving there. we were there in August of 1979, so I am sure things have changed a lot since then. In Acapulco most people had coconut trees in their yards, which produced fruit, and even banana trees, as well papaya trees with wonderfully large fruit. The papayas there were much larger than what we can buy in our markets. Mangos also grew larger there as the weather and humidity was much more tropical there.
