I've never met her, but she always gave the impression of being the girl that was beautiful, but not stuck up. There were girls that were beautiful that if you said "hi" when you saw them would just look at you, and you could tell they were calibrating your social standing before determining if you were worthy of a return comment. Ronstadt always gave the impression that she was the girl who'd say hi to the football star or the dork, without evaluating what it did to her social standing.
Was that your impression?
Just regular folks - the family was well to do, with a long history in Tucson and SoAz. My family was relative Johnny-come-latelys as we first came to Tucson 1926. For cool photos & some Ronstadt history see http://parentseyes.arizona.edu/ronstadtfamily/wagons/shopint1.html - true pioneers. Linda mostly spent her summers in Mexico with grandparents (moms side). Which is to say, we were in different orbits in colliding universes. Never heard any stories about nastiness or the like.
She moved back to Tucson to raise her adpoted children. Supports the community and is still a nice person in many ways, tho a liberal.
Oddly, she never played at Catalina HS that I can recall. After a semester at UofA, she booked to LA and as they say, the rest is history.
In an even stranger subnote, her father got into trouble with the ATF for selling dynamite (this was the 60s where you could buy anything) to a couple of young folks who went back to California and blew up some banks. Thanks for asking, many folks see the famous person, but forget that behind the fame is a person - someone who went to school, had friends, etc. FWIW, I would to have dinner with Linda to compare notes on our HS days.....
