Hmm.. now that I think about it.. they did use a lot of the rock they dug out from Nemesis' pit, and used it for the surrounding area of Forbidden Valley, you can see the excavation marks still

Yeah I agree, I especially love the part in the queue than goes over the bridge near the water fall, as the train comes down it looks like it's going to hit you, but then diverts off.. and that section with the loop.. the wind that hits you in the queue is always quite fun to experience

On a side note, I watched a video the other day from TowersTimes about Nemesis.. I cannot believe the fence that surrounds the helix after the first corkscrew used to be so low! think H&S had a lot to say about that haha
