THE other night in the pub in the quiet seaside village of Courtmacsherry (in September, it returns to its native peace) we had young Brian OâDonovan tell us about what he and his brother Barry, joint skippers of their trawler Sea Venture, caught in their nets a few nights before. He made a great job of the telling. The item wasnât exactly nature, although it was encrusted with nature. It was a World War II mine.
