If they were going to build a new rollercoaster the runaway Butterfield Stage coach would be a great start. Guest board the Butterfield Stage. The stage leaves the town and is attacked by bandits. The race is on. This ride could also be done in a 3D ride.
It would be great to see them bring back the waterfall area of the park. That would be a great place to have the Ozark animals. Besides deer, bear, etc. they could use the waterfall to add an Ozark aquarium.
Guest could view, catfish, stugens, gar, etc.
They could also add and ozark dinning area. One where catfish, deer, bison, wild boar, snake etc were served as the main courses.
