Celebrities who are known to have been at El Rio
but it's unknown whether they actually played the course:
The Navy Blue Angels*
*In the late 1970s I saw them fly over the course so low that I could see the pilots in the cockpits. I could have sworn I could even see their faces. They did not stop to play the course, though.
A knowledgeable source once told me that "Presidents and astronauts" have played at El Rio. Details of neither have been confirmed, although Buzz Aldrin (second man to walk on the moon) did attend the University of Arizona in Tucson.
Did Lee Trevino every play in the Tucson Open at El Rio? It's funny, but at least 3 different people have told me that they saw Trevino play in the Tucson Open at El Rio, and there's even a photo of him on the El Rio Wall of Fame, but it simply never happened. The Tucson Open was last played at El Rio in 1962. Lee Trevino started playing on the PGA Tour in 1967. In my research, I found complete field listings for every year the Tucson Open was played at El Rio, and Lee Trevino's name never appeared in any of them. He did play in numerous Tucson Opens, but never at El Rio.
Other possibilities: Some notable players attended the University of Arizona including Annika Sorenstam, Jim Furyk, Don Pooley, Dan Pohl, Robert Gamez, Rory Sabbatini, Natalie Gulbis and Lorena Ochoa. NBC golf commentator Dan Hicks is from Tucson and once worked at KCEE radio with studios located near El Rio at the time. It is possible that one or more of these played at El Rio at some point during their years in Tucson, but that is also unconfirmed.
