I would rebuild (even though it is still standing) Big Dipper from Geauga Lake, I'm a sucker for wooden roller coasters from the 1920's and I drove past Geauga Lake two times when I was little and remembering seeing it and wanting to go on it so bad. Then I got my first platinum pass and Geauga Lake closed...
I also wouldn't mind the Big Bad Wolf because I love Arrow Supsended Coasters and it always fascinated me and for sh*ts and giggles, I wouldn't mind the Bat from King's Island also.
