Beat me to the Cumberland Falls Moonbows. I've been there on several occasions when they were visible. Only happens at specific times of the month and also under the right atmospheric conditions. I've spent many nights there when they should appear but don't. Great place to stay BTW......beautiful country and great hiking. About 35 miles away is one of the most beautiful places that no one ever goes......a 4 foot wide and 103 foot tall waterfall in this lovely hollow....the best!
