Like the previous poster said, I think you're confusing the Red River Gorge in Kentucky with the New River Gorge in West Virginia. Apart from this video, it's the Red that has been getting all the press recently due to Adam Ondra etc. I visited the New a couple of years ago on the recommendation of a couple of friends from New Jersey who have been to Kalymnos but still reckoned the New was the best sport climbing area they'd found. I've not been to Kalymnos so can't comment on that comparison, but it's certainly a pretty cool spot - tall, well-bolted sandstone walls in riverside/lakeside settings in the middle of a huge broadleaf forest. There are also trad routes intermingled with the sport climbing, so should be plenty to keep most folk happy. It's also a bit of a redneck backwater, so a visit to the local wall-mart can be educational!
