Blue Spring Cave, Sparta, TNhttps://www.youtube.com/watch?v=w6Is71GE9ec
This is an awesome cave. It is the largest cave in TN and the 9th largest in the USA. It is a wild cave (not commercial). Thanks to Judy for organizing the trip. We packed in (4) HID Lights that put out a combined 26,000 lumens. We used a GoPro and Canon Camcorder to shoot the video.
