Nada, zero. I went there to get my stolen car back and haven't been back , it was about 25 years ago. I am far too conscious of the problems Mexico has caused my country (U.S.) that based on principle alone, it is a no-go.
I really enjoy how the night skies are filled with stars. I do not know if its just within the central part of Mexico but I can always see so many stars. Perhaps it has something to do with lack of harsh chemicals/gases floating around the atmosphere like in the U.S.
