Dreamt that I was at Great America and there was a new coaster. From the outside it looked like a knot of square, metallic tubing. The sides of the 'tubing' weren't actually solid, just very dense latticework. It wasn't clear whether the tracks were actually inside the tubes or just on top of them, but the density of the boxing and the knottedness of the layout made the whole thing almost opaque. You could see the sky in a few places while on the ride but mostly it was pretty dark. Eventually I was on it, going up the first hill. I was excited to be on the ride and experience the darkness.
