Alright well I know i promised an update, but I had way too many things on my plate last weekend, so in about 45 minutes i completed the entire track. And i can enclose the ride with two objects, the wall ring, and the dome. Its still rather boring riding it after you come out of the 2nd left, so im not going to release it until i figure something out. It'll probably be adding more supports.
Time for pix!

I know that its all screwy thats because its far away, in the ride it doesn't do that
