Turn your head torch off and it’s so dark your brain will start playing games. You might think you can see your own hands but with .0% light in this cave, it’s only your imagination. It’s also dead silent too: so quiet that if you listen hard enough you’ll hear your own heartbeat. Also, so deep that you’ll have no idea what is happening on the surface, rain, hail or shine this cave is still a dark, tight and lonely place. We’re out at Worley’s Cave in Tennessee and we’re trying new caving routes and tight squeezes into waterways, slides and to find a few new grand openings
