Plus I'm visiting my parents there. There is only one airport in San Diego.
The closest airport is two-hour away.
Edit: San Diego is fairly conservative. San Diego has strong ties to the military bases (Naval and Marines), so that is probably why they take security too seriously. I've been to the bases before, and they give you "death stare". Security is just a pain in the butt everywhere in SD. It doesn't bother me.
