This Darien Lake project is going to be a lot harder than I thought with very little resources on Darien Lake from 1996. I don't have any pictures of DL from 1996 and Googling for pictures of Darien Lake circa 1996 shows very little relevant results. I'm trying my best to help out Six Flags Astroworld on these project(s).
I can only think of two reason why Cedar Fair killed Geauga Lake in 2007, at the time they just bought out Paramount's parks and also Geauga Lake was taking away business from Cedar Fair's flagship park, Cedar Point.
In my opinion, I think that Cedar Fair made a bad decision to buy Geauga Lake in the first place!
