I've canoed some real pretty areas of the USA: Voyageurs Nat. Park, the mighty Mississippi, the Wisconsin Dells-River, the Puget Sound around Seattle, the Skagit, the Deschutes ... the Green River really has to be my favorite.  1st time I floated down Canyonlands really blew my mind more than once uttered and though if I were to die right now I would die a happy man.  

RIP to this boater you died on a sacred and special stretch of USA water.  Condolences to the family and friends.
