George Lucas’ digital empire—The Letterman Digital Arts center, which includes Industrial Light and Magic and Lucas Film is located in the Presidio (which is a national park). They don’t offer tours of any kind, but they do not leave fans without a reason to drop by.
In the courtyard is a statue of Yoda, which is available for a photo op 7 days a week. If you’re in town during the week during business hours, visitors are welcome to come into the lobby, which has lots of Star Wars memorabilia, including a life size Boba Fett and Darth Vader costume.
Big buses are turned away. But the custom private tour in the convertible MINI cooper can go everywhere, even right up to the Star Wars treasure house.
