As a 13-year-old pointed out, the pictures of the falls are a little suggestive. I swear that was not my intention though… Nature is funny sometimes.
Ruby Falls are in Chattanooga, TN and are at the end of a natural/man-made cavern. The only thing that I don’t really get is why they feel the need to have colored lights in there. I think the features (stalactites, etc.) would look better in plain white/yellow light.
