Some tosser in a Range Rover was as filling up a large tub from the grit container opposite my house. 1/2 hour later he was back, he almost emptied the thing ! I Live on a junction at the start of a gradual incline over a railway, cars slipping all over the place. once the snow stopped I went out and put what was left of the grit on the road up the slope, and on the junction sorted, not one stuck car after that and my good deed for the day done.
The traffic spread the grit around and this bit of the road is now clear
