Actually, (and I'll probably get shot for saying this) Cedar Point really did have a "sinking" problem In the past. About 20 years ago they hired American Drilling Ind. (the company has since switched hands many times) to drill samples from the park. I don't know what the results were from those samples, but my guess is that a sinking problem was feared with one of the Frontier Town structures. Of course, this was before any coaster was built back there, and way before the Magnum was even thought possible.
