The Yanks I've chatted to seem to rate RRG as the world class sport venue in the US. It's certainly the big one on my wish list over there if we're talking bolt clipping.

RRG is really good, I loved it. The climbing in itself is not worth the carbon footprint of flying all the way across the Atlantic imo, but combined with the cultural experience of visiting American south light just might make it worth it.
