It seems to me that a lot of people on this board happen to work in the Torrey Pines and Sorrento Valley areas. Those areas have lots of companies and high-paying jobs (engineering, computers, biotech, etc). For those of us working there, CV is a natural choice. It’s very close to work, it has good schools, and it is substantially cheaper (in the past, present, and, no doubt, future) than either La Jolla or Del Mar.
I have friends who live in Rancho Penasquitos, Poway, Encinitas, etc. All of them went there because they couldn’t (at the time) afford CV. So it’s nothing necessarily special about CV, other that it’s really, really close to a lot of good jobs.
