Footprints

Challenge subject today is circular. I've taken several pictures that would fit the bill, but keep coming back to this one. These, and other painted footprints (adults & children sized shoe/feet shapes) follow a route along the pavement near me. I expect to show you how to walk your dog to the local park. I'm not adverse to a bit of thinking outside the box but do wonder if one of our local councillors thought this up. Or are they in every town?
