Huell Howser visited twice and said the place "defies description." He hit that iron nail directly on its head. (The video is well worth watching. You get to meet Michael and see some great vintage photos.)
We wandered a bit but it was more fun to stay with our friend and tour guide, Scott Rubel. Scott grew up in the castle and helped his uncle Michael build it. Scott shared stories of the history of this unusual place, as well as his own memories.
Scott doesn't give tours often, but all the tour guides are great.
