It seems like nothing has been repaired since the park opened; however, they are actually repaired several times each day. I'd bet there is an ounce of original material in any ride.
The next time I'm in the park will because I'm dead and some fool dragged me in there out of pure spite.
They tool out that ride 20 years ago. I’ve been there too many times. I don’t want to go back either. The first time I went there, the admission was $16 in 1982. It’s now over $100.
