I had a stroke in 2021 when I got home after 2 months in the hospital I realized I now have claustrophobia, I could barely put a t-shirt over my head, it was bad. I started watching your videos to help me get over it. At first I could barely turn it on just the thought of watching I felt like I was being smothered and couldn't breath. Now I can watch the whole thing and the claustrophobia is reduced to not too bad, thanks guys be safe.
That looks so much like the Clinch River in Tennessee, I remember boating the river when I was a kid with my uncle and seeing water coming out of a cave just like that!
