May I point out that Canada's Wonderland only has one park to compete with (La Ronde). While the other former 4 Paramount Parks have Cedar Point, Busch Gardens Europe, Six Flags America, Freestyle Music Park, Dollywood, Disneyland, Knotts, etc. Also, while Kings Dominion is not the top Paramount Park, I would bet that the addition of Dominator, 3 water rides, 2 flat rides, and a Giga Coaster (everything added after Paramount left) would make it the best or at least second.
Or last.
