I'm not a regular here. In fact, I don't even boat. But I've read the
book "The Last River" by Todd Balf and have become intrigued by the
story. I'd like to see the National Geographic Documentary, but I
can't seem to find it. What is it called?

I've done some searching on this site and all I can seem to find is
discussion about Doug's incident, but not much on the Nat. Geo. story.

Any help is appreciated.
