I lived in Otay Mesa/South San Diego for awhile. Wouldn’t want to now. Even in East County(lived there a long time), I don’t think I would.
The San Diego border region actually has got a lot of nice residential areas and more springing up. We’re far away enough from the border, and it’s built up contiguously enough, that we never see a migrating illegal alien. I guess they’re still coming in elsewhere. Many areas along border are without fence or poor excuse for one. But we are now importing illegals.
