Seen on the side of a canal barge today at Etruria, Stoke on Trent. Not your usual castles and roses, but very nice image. I’ve actually seen a heron on that stretch of the Trent and Mersey canal. I like the waterlilies that have been included, they are not usually found in city canals though and the water is generally not that clean as there is usually some pollution. But I would say canals, are better maintained than in the past.
