There is also the Weems-Botts house which has been made into a mini-museum & tour site with nearby colonial graveyard. It is a tiny historical colonial house with historical ghost stories (they help drum up tourism dollars for the upkeeping of the house, but they are age-old "historical" ghost stories).

A group I was in, paid for an overnight sleep-over at Halloween. We had fun amongst ourselves telling ghost stories and goofing but nothing happened ghost-wise, go figure huh (and it's not a theatrical haunted house, they don't stage anything for you, just check up on you). We brought a ouija board just for fun (none of us really believed in all that, but it was made by Hasbro and we thought it would add to the Halloween atmosphere to play with it in a "historically" haunted house). Funny though, they asked us not to use it, and so we complied.
