We saw this gigantic structure from the road, but it was impossible to stop to photograph it, so we pulled off and ended up almost on top of it, the only vantage point I could get. It's located at a place that bills itself as a “Smoky Mountain Waterpark Resort.” I guess this was some kind of waterslide.
I had posted another picture of this a while back, in totally different colors. Part of the attraction of this thing was that it constantly changed color, which looked great from the road.
