What a day to go to Cardiff! A little peaceful shopping perhaps? A jaunt around the celebrated castle ruins and reflection upon medieval times? Not on this day, anyway. Yes, we could go shopping, yes we could go around the castle, but our attention was drawn principally by the feel of carnival around us. Drummers drummed, streets were crowded, restaurants full. The colours on display were mostly red and green. What was the occasion but the English and Welsh Rugby teams playing off against each other in the Millenium Stadium. You’d think it was winter but that kind of enthusiasm generates its own warmth.
