I also worked for Ted Sarbin at Bally Systems in Reno (in 1979, I think). I'd bet there weren't many private pilots named Ted Sarbin living in California in 1972 (his dad, same name, was a famous psych professor). Furthermore, this airport is consistent with the sorts of destinations he liked: fly to small airport in the Sierra's, eat lunch, fly back to San Jose (or in this case, lacking a restaurant at the airfield, maybe skip lunch? :-).
