Spring has sprung here in Cornwall. The daffodils are out and the sun is shining between the showers.   What better time to take to the Lizard  Peninsula Coastal walk, with a tea-break at the Cadgwith Cove Inn, an old haunt of Grandpa and his shipmate, Buller Arthur. A roaring fire and a warm welcome with loads of interesting old photographs of life-boat rescue and fishing.
