I have had two very short LDRs in my past, and they have never worked out. But now that I am older, I think I would be more willing to try. Initially I wasn't digging it because I like to be with the person I am with, hang out, get to know their personal surroundings and such. But now that I am getting older, I can see the benefit of really getting to know each other on a deep, intimate level. I wouldn't want to have a LDR for a long period of time, I would need to see a light at the end of the tunnel, and that always gets sticky with details of how, when, etc. I personally have never relocated to be with anyone before, and I think if it ever came to that, it would be a hard decision to leave San Diego. I don't even know if I would do it, honestly.
But anyways... good luck to all the people in LDRs!! May you find happiness
