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 court yard 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 convertible MINI cooper can go everywhere, even right up to the Star Wars treasure house.
