Screw you guys, I would go to the future.
I will be heading over to Cedar Flags Magic Mountain to ride Goliath Senior, the worlds tallest, fastest, most loopiest, and highly overbanked turns and drops roller coaster and rapids ride. Its fudging insane!
But if we are restricted to old times sake, I would go back to Riverside Park in Chicago and Palisades Park in New York, Steeplechase Park and old school Coney as well. Now those are insane rides...
