We returned to the main drag, and had some lunch. With the cooler weather, we were enthused to press on up the Delph flight of 8 locks, and then on to another Silver Propellor location – this time the Southern Portal of Dudley Tunnel. The silting in the top pound was so great that we couldn’t get within line of sight of the tunnel. We managed to get to the bank a little further back to see the portal. We don’t fit through that profile!
