Oh dear, I am now mourning for that whin (dolerite, the form basalt takes if it cools underground). Roadstone! Still, better than landfill, which is what our Meeting House warden did with Kentish Rag from the garden. I might feel different if I had not seen what the Italian lessee of one of the flats I used to live at had done to the Kentish Rag there, which I have hankered for. He's painted it white! If I'd known he had that in mind, I'd have offered him my concrete and swapped.
