After reading this post, I decided to pay a visit myself. Tickets are free, but you give them a driver's license on your way in, so they get your address, even if you give a fake one when you register for tickets. It's hard to argue with the published mission, it's lots of motherhood and apple pie. We met with an educator who talked about the architecture and the buildings (officially called "volumes"), but when we asked about the ownership, she basically repeated boilerplate language about it being a 503(c) non-profit with global reach, so no specific names are mentioned.

On a side note, the trail around the grounds is really muddy now and not well marked in some places (we thought we followed the map, but the trail just sort of disappeared into another property). It's not huge, but it's a nice diversion for a couple of hours. I guess you could plop yourself in the library or commons and use their wifi if you wanted to linger over a cup of (free) tea. There was a piano concert last night, so the main amphitheater was closed for setup, but it's really beautiful, from what we could see from outside.
