This topic reminds me of Bob Carey's book "The Adventures of Jackpine Bob."  The book is worth every penny for the final chapter.  But do yourself a favor and DON'T skip to the last chapter.  Read it all.

In the book he talks a lot about paddling with his wife.  That's all I'll say so I won't ruin it for you.  It is a MUST for those who enjoy paddling with their spouse.
