Before I answer DarienLaker's question, I'd like to point out that my question was answered incorrectly:

The correct answer was Skytrak at Granada Studios in 1997.
Now, on to the answer for DarienLaker's question:
Iron Wolf at Six Flags Great America in 1990 (Now Apocalypse at Six Flags America since 2012).
What is the oldest ride at Canada's Wonderland?
