What the duck?

Quite why there is a duck on a sign saying no climbing I don’t know. It’s at the southbound Tebay services on the M6 where we stopped on the way to Liverpool. The weather had been nice in Edinburgh but gradually got cloudier and slightly damp as we went south. The extra is of a tree that caught my eye with the recent ploughing showing up in the bright light quite close to Lamancha.
