Pounding the Pembrokeshire coast on a scorching Sunday has to be one of the great weekend activities. There was enough breeze to make it comfortable and to give a texture to the inky blue of the sea. The heat unlocked the evocative smells of the cliffs -- pineapple weed, chamomile daisies and dusty heather. I felt like I could have walked forever. Making my way back inland I lingered in St Davids. With its ancient stone roofs and pastel renders it was one of those days where you could have been in the south of France not the west of Wales.
