A practical test

Mrs P and I walked up Corb Glen in light rain. On the way we passed through this gate. The catch opened easily enough, but it jammed and I couldn't shift it back to fasten the gate. I struggled for a minute before recognising the significance of the rock on the post. One blow freed up the catch.

On the way back we saw a cyclist coming from the direction of the gate, and when we got to the gate the catch was left open. He'd failed the test!
