Years ago I worked in Queretaro, and there was a flight school on the field. They had a couple of C172s and maybe a twin. At the time it would have been a good place to train because there wasn’t much traffic and the weather was usually wonderful. I don’t know if the school is still there or what the traffic is like these days, but maybe it’s worth investigating.
I enjoyed living in Queretaro. The people were wonderful, the city offered good recreational and workout opportunities, and nearby there were other interesting cities to visit.
