For some reason I have got a trip to Mexico City in my head. The area's population of over 21 million makes it the largest in the western hemisphere. As well, it is an important financial center of North America, and the eighth richest city in the world. Importantly, it's relatively close trip being only two time zones away. We love urban environments, so I guess going there is a must. I can't say why I never really thought about it before!
I was checking out Google's Street View of the Zona Rosa, not far from the Centro Historico, as it's probably where we'd look for a hotel.
