I love San Diego. We travel there for work quite a bit. The San Diego residents may be a little familiar with the aircraft I work on since there was one floating in the bay at the end of last week.
I have visited and love all the stuff mentioned above. I would also add Frank the Trainman if you like postwar Lionel. They sell both new and used and have quite a bit packed into their little store.
Sorry for the small disruption...
Goshawk, I looked for your email in your profile but could not find it. I was on the program in the early 2000's. I got to fly the simulator in Kingsville once. I was invited on a carrier trap and shot, but that was when the program was experiencing a lot of compressor stalls and I declined.
Shoot me an email if you are interested.
