Everyone has got to have a few coasters you wish still existed for whatever reason! For me, it'd have to be:
Drachen Fire. Despite how rough it probably was, it was the coaster that made me love coasters, and I never even came close to it [:(]
X. I wish I could have ridden it before the rotations were controlled.
Every ride at Opryland.
I also hate to say this as it seems to be a sensitive subject, but Intimidator 305 pre-trim. *winces*
*Oh yeah and the Crystal Beach Cyclone.
