March 2010     Continuing north along the Grand Union canal, visiting Leighton Buzzard, Milton Keynes and Stoke Bruerne.           Aylesbury Canal Basin - worth the trip down the Aylesbury Arm for the friendly welcome from the Aylesbury Canal Society.   The pretty Aylesbury Arm of the Grand Union.             A study in concentration !   A view down the rural stretch of the Aylesbury Arm.             Back on the main line near Marsworth.   Ivinghoe Beacon - a short cycle ride away.             Moored up at Water Eaton - near Bletchley Park.   A modern aquaduct over a dual carriageway outside Milton Keynes.             The rather splendid Soloman's Bridge, Cosgrove.   Examining the boat weighing device at Stoke Bruerne.             The very long Blissworth tunnel - all 3057 yards of it. This is the central section, that has been rebuilt using concrete.   The skipper looking calm... but feeling nervous! The blurred roof is caused by the darkness forcing a long exposure - we're only really going about 2 mph!
