note Foothills Paddling Club out of Greenville
is pretty active. They run a lot of trips. You could start on the Lower Green and work up to the Chattooga and other stuff.

If you can make it up to Bryson City the week of July 4th (and weekend before and after), Carolina canoe club has a week of rivers event that would help you meet people to paddle with.

Both groups have Facebook pages and friendly folks.
