I have guided on the Gauley, Gore, Clear Creek, Ocoee, Cross Mountain and many other rivers. I would like to mention 2 sections that have not been talked about. Clear Creek Canyon at 1500cfs is near the limit of what is possible on a commercial trip. It has a 1.25 mile section that drops 192 feet in elevation. Way more deadly and challenging than gore or the Gauley. Also Cross Mountain at high water should be on the list as it is more technical and commiting than the Gauley. Just my 2cents.
