It might be still there. I've never really looked.Are they still selling that fancy Knotts coffee table book? Might pick it up if so. There is some Disney level rich history there that I find appealing. Probably grab some Mrs. Knotts fried chicken (and boysenberry pie) and just keep hoping the chicken gets better.
Walt and Walter had a friendly competition between them. Knotts had the first hidden queue that Walt used for Pirates. There is still a lot of history that Cedar Fair hasn't completely erased yet. Not sure if most things would have survived if Disney bought them out.
