There's not much traffic along the canal during the winter months so I was intrigued to see a boat in the distance, when I was taking 'the scenic route' back after doing some errands in Shipley. Getting closer, I realised it was a Canal and River Trust's working barge. Workers were busily pruning the trees and shrubs on the thin fringe of land between Salt's Mill's outbuildings and the canal. It's surprising how quickly these saplings spring up. Left unchecked, their jutting branches start to narrow the navigable waterway, which is only just wide enough for two boats to pass, as it is. How many people does it take to trim a shrub? In this case, at least seven, including the guy steering the boat and another trimming some saplings on the towpath.
