My wife was born in Hemingford Grey in Huntingdon and we knew and loved its river, the Great Ouse. We sat by it, we meditated by it, we walked its banks, we explored it by canoe, skiff and pont. I knew its mills, its sluices, its locks, its churches, its meadows and, further afield, its fens. It became part of my life.
