Doesn't Cedar Point still own the land in the Irish Hills(a great area, I may add)? A theory is that they were going to put Gemini there, but they bought Valleyfair! and put the Gemini at Cedar Point(there was a thread at GTTP on this, I'm not a genius).
I doubt Cedar Fair would ever build in the Irish Hills. Cedar Point gets plenty of revenue from the metro Detroit area(all the kids at my school go at least once a year).
