Atchafalaya Houseboat

I wanted to see this PBS program tonight but missed it. After reading that book on the Ivory-billed Woodpecker I've wanted to know more about the hardwood swamps of the Delta wetlands. There are supposed to be pockets of swampland all along Arkansas's Cache and White rivers, mostly second growth remnants of the hardwood cathedrals that used to be there. And I've even heard of river people in some parts - nothing like Bayou Chene in LA - but still... It would be nice to know more. What this history is, what still survives...
