I know this is an old thread, but my boss owns those 2 double decker busses. He said he bought them at Kings Island when it was owned by Taft. One of them is still parked on SR 32 in Mt Carmel near Eastgate Mall in between Grays Towing and High on the Hill. He has the other one on his property.
Id like to get some more info on this, hopefully some pictures when they were in service.
I can take some photos of the one on 32, but its in pretty rough shape.
