I was at the Library about 6 years ago - that part of CA is very nice. when I was there (the place was empty at that time, I got there when it opened in the middle of the week), I was told that they will actually be building houses down the hill from the Library - that the "no development" lease on the land when it was granted to the Library expires after a certain amount of time.
Can you imagine what those homes will sell for?
