I checked Hearst Castle. Ah, one of her's I've little sympathy for, though as a purposely overdone extravanza I've got to say it works. Much has been added to the complex since I was there, but I remember the overcookedness. Still, I liked parts of it. The indoor pool, the indoor pool...
Speaking as I was of overdone on purpose (hard to believe the same woman designed all this) -
Wiki on the development of Hearst Castle:
The land I was referring to that at the time I saw the place was extensive..
Still, I grumble, I prefer similar land at Point Reyes National Seashore, which has no damned faux castle on it.
