My wife Tina and I went down to Kentucky for her birthday. We actually hit Kentucky on our way back from Tennessee. Our bucket list of things to do included going into a cave. Neither of us have ever went inside a cave before. What a cool experience. We enjoyed it so much so that we wondered if there are any other caves you would recommend? Crystal Onyx is majority of the video below. Michigan couple Scott and Sara Sendtko purchased the cave back in 2010. The cave was first discovered in 1960 and there were some bodies found in it! It hasn't been open to the public very long, but man is it a cool cave! We actually had Scott as a tour guide. Super cool dude! The one nice thing about a pocket sized camera is you can take a video to record your experience.
