The title of this post is literal rather than metaphorical. The sixth and final gate on my walk was accompanied by a cattle grid and so the way, at least for animals, was indeed barred. I started the posts for my walk this week with some images of walls and so as I approach the end of the walk it seemed appropriate to include the walls I found at this last stage.
The sound of this gate is also included below.
