Mexico City is a third world cesspool, of course, and anyone who's been there knows this, even nadin. The new air port, though, is very nice. I haven't been there for about three years or so, but one thing I always liked at the air port was when you arrived at customs, you pressed a button. If you got a green light, you just walked through. If you got a red light, they would take you apart. I've got a 100% green light record, but once a guy I was travelling with hit a red light, and it took him forever to clear. It's a neat game of chance. There may be other air ports where they do that, but Mexico City is the only one I know.
