Well I understand alot of you are scared of carnival rides, just like I am, but a couple things to look at here, just real quick. Skyliner is a portable wheel that could go on a flat bed. Rockin Reeler was also a portable ride, same with Wacky worm, most of the rides in the children's area. Also at CP, the alpine Bob, Matterhorn, is portable, and Wildcat is pretty much the same design as the ride that derailed, and Wild Cat is also portable. I mean it totally depends on the care that is given to the ride. I think alot of people would have have realized there were on a portable ride until they were told. I just have a problem when I go to carnivals, and they have an "Omegatron" style ride that is placed on a downward slope of a hill and are using wood to level the ride, very scary if you ask me.
