Just to ensure I stay fit and healthy, TPBTT has insisted that for the last 2 days we take a healthy walks lasting at least an hour. Yesterday we have found an old disused (I think) railway line that runs alongside where we live and we decided to follow it to where a road crosses it. Today we crossed the road and followed it to the end. Unfortunately the A1 crosses it so we never found out where it ends. I think it is an old rail link between Yorkshire Main and Markham Main.
