Wow.
I really hope we don't Scream's color scheme. It would make absolutely no sense if it was themed to some random thing like that.
If the park really does read these forums, take it from me; an employee who listens to guest's opinions every day, and has great ideas of his own:
Theme this ride western. And please don't half a** it. You have a real chance with this project, please, for your own sake, don't mess it up.
