If you want a roller coaster experience that will physically hurt you, try the superman-position ride at Coney Island (a ride where you are held flat, chest down, looking up/forward in the direction of travel), then follow that up with a ride on the Cyclone. Either would have been okay individually, but in that order after each other? Fucked up my neck real bad.
I was there with a friend, and we both agreed we wouldn’t have gone back on the Cyclone again right away, even for free, which was a new experience for both of us. Normally EVERY rollercoaster ride, I want to try it out again immediately.
