I hate to tell you this, but this thread really won't get you any answers. I'm sure there are some pretty good squats in San Diego. Not that you'll hear it from anyone on a public forum. Seriously, telling you about squats on this forum would be equivalent to snitching them out to the police, or anyone else who cares. They could get shut down if the wrong person read this. You should probably check with some people in real life if you can. If not, try to connect with the right people on here.
