The largest wildlife pond at the end of the track, with “oil filter processing” at the suggestion of @Shepherdmanswife. I can’t decide whether or not I’m a fan of this treatment but it certainly adds interest to a somewhat gloomy autumn scene. The pond hosts a variety of water fowl, including a couple of swans – I am pleased to report that that swans and dogs have a healthy mutual respect for each other, and so all four should say out of trouble.
