The whole state of Sunday night television was much different than it is today.

Other than Disneyland, it was my first exposure to an imaginative design like that. I got the idea for the Berlin sector from the black-and-white striped guardhouse.

We all have a little bit of espionage in us, but back in the '60s the James Bond movies were all the rage, and it was just a lot of fun.

The whole place is a practical joke.

It was this dark, secluded place with lots of little rooms and passageways, and you just knew there were real spies and espionage taking place.

I've become friends with a number of CIA agents who come here, but they really don't share that many stories.
