The Elephant Steps ....

..... are a shortcut up to my daughter & son-in-law's house from my caravan. They're made from very large local slabs of schist. I found out to my cost that the sap from the sycamores can make them very slippery when it rains. I slipped straight backwards off the bottom one, and it took weeks for my back to recover. Acupuncture did the trick though and it's come right. I'm still using the shortcut, but will be taking the long route when it rains!
