After having done the Nahanni two times, I thought it was time to read this book.  It is a great adventure read - this guy is going up the river which I cannot imagine doing.  Definitely "old school" paddling and poling and lining up the river, only portaging a few places.  It sounds like several of the rapids had been much harder in the old days.  Haven't finished it yet, it is a very "easy reading" book that I think anyone would like.  The last printing was 1970 I think, so it would be hard to find.  I borrowed a copy from the library.
