The top of a fence with frost on it. (Does exactly what it says on the tin. Or title, whatever).
I should apologise, by the way, that this isn’t a “Slade” photo. I’m afraid I just haven’t had time to do one today – I was out all evening at an ordinand’s dinner, straight after work. I do apologise, I’ll try and make a bit of an effort for the last couple on Monday and Tuesday 🙂
