I wanted to combine elements of a traditional rollercoaster and a scenic ride, and this section of my server world fills the bill! I adapted some existing build to add this fun ride, so there's rails off to nowhere, and I assure you the terrain, amazingly, is normal generation! I've included a schematic and a quick mcedit world paste. The biome is savannah which adds a distinctive look to the area. 

I've included some fun drops and underground passages and there's a lot of little heads to find and count! I wish Minecraft physics allowed more variation like proper loops and Immelmanns! Apologies for the phone-quality video, I can't afford to upload HD videos.

Comments and suggestions welcome!
