My first trip to KI was 1987. I was too little to ride The Beast. I recall my brother riding Vortex (it was it's first year in operation {I believe}). He bought one of those "Baby on Board" like signs that read "I survived The Vortex" or something like that. We joked that it should have read "I survived The Vortex Queue". He and my father must have waited 2 and 1/2 hours.
My second fondest memory of KI was my first ever ride on The Beast (must have been like 1991). However, my fondest memory of KI was my first ever ride on The Beast at night! This was only a few years ago. I can tell you that I was about 27 years old and for the first time in my life, I was actually convinced that I was going to die. Literally. I nearly had a mess in my pants.
Best. Roller. Coaster. Period.
It will never be topped.
How did I find KIC? I owe this to The Interpreter. He had mentioned a few months ago on another, unrelated message board, that KI would have a "Major Announcement" soon regarding the 2007 season. He was talking about X-Flight/Firehawk but it took Google and my finding this site to figure out what the devil he was talking about.
