The "billing" is the local name for the clump of trees that sits atop that hill in the photo below. It is a well-loved, and well-visited landmark in Rawdon, Leeds, West Yorkshire. It lends its name to the local tea shop and to several roads.
The photo below is taken from Bayton Lane, which runs along the back (i.e. on the far side from the car parks, arrivals and departures, etc.) of Leeds Bradford airport.
