Gauley season is Sept. 9th to Oct. 16th.
Schedule here: 2011 Gauley River Whitewater Releases
You could go down to Chile, Costa Rica, Australia or New Zealand if you desire...after the end of Gauley, most guides stash the commercial rafts until the spring, unless they are headed abroad. Just a sad reality of the seasons, my friend.
I hope you like to ski.
