  • Elaine Williams "My daughter and I attended the ghost tour, and we really enjoyed it! We've both been in the house before, but it was exciting to go by night and experience the rooms-- especially the "doll room." Nick does a great job of creating interest and entertaining the group, plus we learned a lot about the primary family and some of the items held in storage. We recommend this fun tour!"

  • Cute historical little cabin. Ohio historical markers at the site, explaining the cabin, as well as the Xenia tornado of 1974.

    Brian Dible

  • It is a facinating place full of historical artifacts and memorabilia from all over Greene county. Nifty model railroad display with scenes from 1930's to 1950's.
