Ruby Falls

Recently I’ve been going out quite frequently. Last week, I drove north along I-75 from Gainesville via Atlanta to Nashville, the capital of Tennessee. The next day, I headed south to Ruby Falls, located on the border between Tennessee and Georgia. What was quite interesting is that there is a one-hour time difference along this route, so I got to experience the transition between standard time and daylight saving time again. Ruby Falls is somewhat similar to the underground limestone caves in Yishui. However, the underground waterfall at the end is quite distinctive. There is no boat ride inside the cave; you simply walk for a while before reaching the waterfall. The waterfall is illuminated with many colored lights, and you have to take photos quickly because the main lighting only lasts for a short time.
