Last time we went through the locks - which won a £50,000 prize for some lady artitect who told the keeper off for pointing out the lack of a raise push the gate stone as such stones would spoil the symmetry. (She also used a pretty but btittle brick that shattered easily as it looked nice.)
Anyway going through a couple of years back we noted the lack of grease, graffiti and rubbish in the water and, in broken bottle form on the land but to add insult to injury (with the lock keeper long gone) a Bw crew were hard at work getting the grass out of the cracks! When we asked about grease, rubbish, graffitti they turned real funny as it was not their job and until money was found by the local council it wouldn't be as BW on't do that stuff round here.
By the way what on Earth is a certain avatar dragon doing behind the newspaper?
