Yes, it is scheduled to open in Spring 2006.
The name of it is Expedition Everest. It will be the tallest point in Florida. The coaster is steel rail and weaves in and out of the mountain. It also will go forwards and backwards, but from what I have heard, will have no inversions. The storyline is based on the the Yeti, a mythical beast in Asia ( more commonly known as the Abominal Snowman). Story goes like this... you are on a train sightseeing in the mountains when this Yeti starts chasing you. I have heard that the ride will last right around 3 minutes.
