Another one

Is there some sort of footwear vortex down our street? A discarded boot on the patch of waste ground just along the road from the last one. And also in the picture the yellow flowers of that prolific coloniser of rough ground, the Oxford ragwort. Allegedly it first spread from Oxford, where it escaped from the grounds of the Botanic gardens, along the ballast of the rail network. It now uses the gravel alongside our roads to spread to all but the furthest north of Scotland. While the flowers are bright and colourful, the plants are poisonous to livestock and therefore probably on balance not 'a good thing'.
Quite what the story of the one boot is, I don't know. Presumably not the work of some travelling salesman, still dining out on the day he threw a kettle over a pub, throwing it over one of the office buildings.
