I wasn't aware until reading that article that the Aguila plant was in Cuernavaca. My wife's great aunt lived there, in the lap of luxury.
She attended our wedding in southern NM, 43 years ago this month. My grandfather, a fairly wealthy man, was talking with her, and asked how she was getting back home to Cuernavaca. She replied that her boy would be picking her up. When my grandfather said that it was nice that her son would drive her back home she informed him that her boy was not her son.
My new bride and I had already departed, but heard later that my grandfather's jaw almost dropped to the ground when a Rolls Royce pulled up and her uniformed chauffeur got out and opened her door. Life was good for some ex pats living in Mexico in those days. My wife's great uncle had made all his money in South American mining.
