I am way late to this discussion - but something like that happening is one of my worst nightmares. (Seriously, I have dreams about that stuff happening all the time, I am a little sick in the head)
I don't mind getting really wet (though I don't love it either)
My last trip I made to Cedar Point with the rest of my family in 2007 the younger members really wished there was some sort of log ride, because many of the coasters were still a little too intimidating for them at that time.
