Scared, but knowing it was possible to run, Pat Keller geared up for a first descent of Ozone Falls in Cumberland County, Tennessee.
In case you're wondering, there is a good reason Keller didn't capture video from his helmet camera. The camera ended up at the bottom of the pool beneath Ozone Falls, which has been called by kayakers as the Holy Grail of the Southeast. Watch the incredible drop:
"The impact's exponentially larger the higher you get...talking bone-breaking, face-smashing, any of the bad things--knocked unconscious, break your neck," Keller said.
So Keller ought to be thankful that his only casualty was his helmet camera.
