Many a good hanging prevents a bad marriage.

What sets a canoeing expedition apart is that it purifies you more rapidly and inescapably than any other travel. Travel a thousand miles by train and you are a brute; pedal five hundred on a bicycle and you remain basically a bourgeois; paddle a hundred in a canoe and you are already a child of nature.
-- Pierre Elliott Trudeau
