Walking on a section of the Tarka Trail which runs along a section of former railway we met a large herd of cows that had strayed onto the line through an open gate. As we walked along, the cows naturally walked in front of us but were hemmed in by the fences on both sides. We kept well to one side of the path but the cows would not take the hint and break back past us despite becoming more anxious as they got further from their field. Eventually, we came to a gate across the trail and they had nowhere left to go. I slowly worked my way up by one fence (with Mrs N tucked in well behind) and they finally got the idea and started to break back past us so we could get through the gate. It was just a question of staying calm, making reassuring noises and not making any sudden moves - just giving them time to work it out.
