Grand Union Canal, near Blisworth
North end of the Blisworth Tunnel. The tunnel is 2.8km long. The light you see in the photo is from a narrow boat coming through.
Grand Union canal at Stoke Bruerne, South of the Blisworth Tunnel.
Quite a few of these narrow boats are privately owned, and are like ling, narrow caravans. Ultimately I would like to have a holiday for a few weeks on one, travelling at 4mph. I hear Google is doing a Canal View for Googlemaps. Which is nice.
Lock 2 on the Stoke Bruerne flight of 7 locks that drop the boats into a valley
