you'll want to pick up one of these: http://www.nccreeks.com/
email me when you get here and I'll try to steer you in the right direction.
what kind of stuff will you be looking to run?
fall is usually dam release sutff, lotsa weekends on the Gauley, and waiting for tropical storms - of which there have been a lot in the last few years.
not a bad time to come for Green, Cheoah, Tallulah, Ocoee on releases, and more with rains.
it's all in the book so you can start making a list of what you want to hit...
