Just something fun. There are many "dead" attractions at Disneyland that have come and gone. Many of them in Tomorrowland. Photoshop one of these rides or something in their "ghostly" state haunting an existing ride in it's place.
Haunted Mansion doesn't really count !
I'll start with the "Haunted Skyway" with "resurrected" Skyway Buckets still going...
