We landed in Mexico City (DF) - we fell in love with it. It's cultured, cosmopolitan, and friendly. I was surprised that nobody spoke English. Not that we expect people to do so, but it's so common wherever we go. We have enough Baby-talk Spanish in our mouths to get around. We also had phrase books to help (that was before smart-phones).
We went to Teotihuacan - getting there on the local buses without the benefit of fluent Spanish was an adventure but we did all right.
Then we took a Bus to Guadalajara - In Mexico they have busses that are like the first class section of an airplane inside. Huge seats, refreshments, and so on. There is nothing like that in the US. (We've also taken "Chicken Buses in Mexico and they are a different kind of fun).
Then on to Puerta Vallarta which was very pleasant but a little too touristy for us. I grew up near Fort Lauderdale Florida so tourist towns are like home - and I travel to see different things. Still the people were nice and there was enough to see and do for a few days.
Where else but Mexico can you see these policeman outfits? In a big park in downtown DF
Our Lady of Guadalupe. This is the real thing, and the best picture I could get - you pass by on a moving sidewalk because there are so many people who want to see it.
They were having a festival in Guadalajara - plenty of great music acts, this was one
