if you go you will possibly meet this aging hippie named John, who was the volunteer running the place when we went.
I slipped him a 20 and we went on a very small tour with just 5 people. We got a very good view of the entire place from top to bottom. There was also a short historical movie that they displayed inside the guy's old living room.
Of course there's a mysterious legend about a lost lover and a man Driven Crazy by unrequited emotions.
