ON the first night of the Pittsburgh Investment Conference last weekend legendary American football team the Pittsburgh Steelers were having a party in the bar of the hotel where the hundreds of Irish businessmen and State agency staff were staying. Some of the more tired and emotional members of the Irish delegation were caught attempting to chat to the very exotic ladies surrounding the footballers. When it was brought to their attention that the ladies in question were attached to the extremely large men propping up the bar, most beat a hasty retreat.
