This is from the Fenwright Manor(Haunted House Ride) blog

The future of this attraction is in jeopardy, all the concept art and protype props were lost with storage. Not to mention that serious captial is needed to fund and build this ride. It's been off and on since May 1996, and always gets put on the back burner. I don't know if this will ever get built and it's hard for me to ask for investors or look into getting a loan or grant.
