I must add, however, that ground subsidence is a very real problem in some parts of the world. It happens when a local aquifer is depleted to the point where the ground begins to settle. In San Jose, the ground has sunk 8 feet in the past 100 years. In some parts of the area, the ground has sunk up to 20 feet in the same amount of time. Unfortunately, this process is irreversible.
Ground subsidence of 6 inches has been blamed for sending the Whizzer and Great America to the scrap heap.
Whether or not this is true for the Whizzer or any other coaster, the problem is a very real one. Why the same subsidence wouldn't wreck the Demon is puzzling. Then again, they are completely different structures.
To shed light on whether or not this is a rumor, I don't think the aquifer around Sandusky is in any danger of being depleted. In fact, geologically speaking, the land in the area is still rebounding from the last ice age. Given that, the opposite should be the problem!
MAGNUM ISN"T SINKING!!!!!!!!!!
no offense, but i am getting fed up with that rumor. damn the people who made it up.
