It was a case of "stop the car!" this evening. While Blip-hunting I saw a grouse, just like on the famous whiskey bottle dart into an opening between two hedges. Of course, the bugger was long gone by the time I got my act together, but the opening led me to this gate which is an old entrance to one of Drogheda's two cement plants.
Not sure what they're guarding, but I imagine the guard dog isn't terribly busy.
There was about an acre of old rusty scrap iton behind the gate.
