Thanks for the Queretaro report. I've been there a handful of times in past decades. It has a sizeable foreign-born population because of the large number of international corporations. Primarily, I view it as an industrial city once you get away from the historic center. It's well-located to visit other cities in the Central Highlands as well as a relatively short jaunt to Mexico City. I've traveled extensively in Mexico for many years and though each of us has different criteria QRO wouldn't be on my list of places to relocate. It's good to check out the possibilities before moving; it's the smart thing to do.
I returned, yesterday, from a two-week trip in Mexico: Mexico City (CDMX), Toluca, Atlixco and Puebla (in Puebla State), and Tlaxcala.
