Close call!

Still up to my eyes editing all the photos to go with the choir songs. Will have my own life back after Thursday night, yaaay! 
Was walking along the canal this morning  and went to cross over one of the locks as per usual then  boom just at the last minute I realised that these plonkers in the above boat had only shut  one side of the lock!!!  This is surely dangerous, I always thought you closed both sides of the lock. I can't swim so if I had taken a header  I would have sunk like a stone. Mutter mutter mumble mumble .
