Hello,
That quiz was great! I got a 24/25. I missed the question about Wipeout beach. My first instinct was right, but then I psyched myself into thinking it was 96 instead of 98. Hmph.
I noticed that one of the questions identified 1992 as the last year for the monorail. The park history page of this web site agrees with the quiz. However, that is actually not correct.
The monorail ran in 1993 as well. I wanted to check my archives before posting, and I did find this is indeed the case.
Not to get off-topic or anything (I suppose it does fall under "PKI Knowledge"), but I'm also thinking Viking Fury opened in 1983, not 1982. I'm not sure about that, but that just seems to be how I remember it. Unfortunately, all I have on that is an old souvenir map that says "Swinging Ship 1983" on it. Not the most reliable source as you probably know.
