The pictures are amazing and I am sure it would be fun to body-surf through those rapids.
If you happen to like white-water kayaking, you might try the Broad River north of Athens. There's a great outfitter that has amazing prices and knowledgeable staff. There's also one other great quirk about the river. Most of it is maybe 2-3 feet deep. There are numerous places where I've personally gotten out of my boat, walked back up through a set of rapids and gone again for the fun of it. Makes for a good trip at any experience level. Not to mention the beautiful scenery.
