bad expodential scale definition: The difference between 1 and 2 on the scale is 10, but the difference between 1 and 3 is 100, 1 and 4 is 1000 and so on...
wow, i love those slider rides.
we used to have 2 of them at my local ski hill (blue mountain), but a bunch of people got themselved thrown off the track or something so it had to be take away
nice theming...
except on the 1st pic, the rocks look a bit out of place, i think it would look much better if you extended the mountain all the way to the station...

and supports for a roller coaster probably dont hold up well as a building, so it could easily make them fall down....
although in japan where there are alot of earthquakes, they probably make their coaster supports really good.
