First dig a square hole 10x10 about 5 blocks deep. Then raise a 10x1 line 2 blocks high. Now construct a ride that goes through that 10x1 path. (almost done!!!) Now put glass walls on the blocks beside the path (so they touch). Now you can see the ride!!!!!!!!!!!!!! You can put large rooms underground too!!!!!!!!! [/size]

huh, never thought of that, but i might give it a try sometime and see if i dont drown
