Over the bridge

I have taken graffiti as the cue from Picturemull's guide image for this week's MM.
I often cross this bridge over the railway line on my bike rides as it is a convenient 'escape route' from town.
The graffiti often changes, and recently it seems to have become more abundant. There are  several references to the covid pandemic and support for our NHS workers, so it's not all bad. It's actually quite colourful - see the extra.
