We just got back from the tour. It was a nice little tour, even though we weren't able to go in all the rooms. Couldn't even go upstairs at all. But they are in the middle of doing quite a bit of work... restoring some rooms and such.
I asked about what I heard about the Underground Railroad... and they said that they have heard the same... but haven't found any tunnel entrances and such to support it yet. Brittany asked about the rumors that the place is haunted. And basically all that was said about that is that there were some experts (ghost hunters and such) there but they came up empty.
But like I said... nice little tour. It lasted about an hour. Cost was $5.00 per person.
