Day visit to neighboring Queretaro

A couple of weekends ago, we took a little drive (only 45 mins) to the neighboring City of Queretaro, which was declared a UNESCO World Heritage Site in 1996. Definately a pretty town, but architecturally not quite as spectacular as Guanajuato or even San Miguel. Nevertheless, for a city with a population now around 750,000, it's very clean, quiet and pretty much crime-free. There are many parks and plazas that are a pleasure to stroll. It's also a fairly modern city, with a good industrial base, plentiful employment, and a new international airport. Notwithstanding the foregoing pleasantries, it most likely is not a place we would decide to settle in. Not much else to say about it - just the usual "it's a nice place to visit, just wouldn't live there". No compelling reason, other than we just were not 'wowed' by it.
