My first 'proper' fellwalk was when a teacher took me and a few other kids over the Langdale Pikes. It was Easter 1974, and we ran down that scree much faster than we would ever have been able to run on a road. The size of the stones was perfect, so that you literally 'went with the flow', but you had to put the brakes on before the stones ran out. Easiest way to do that was to fall back on your bum. Caused absolute ruin to a pair of boots though!
After a few more 'runs' in the 1970s, I learned more about the archaeology of the scree, and realised how much damage me, my pals, and everyone else had done. I've never been down it since, and never will again. Leave it well alone!
