Before we left on vacation some two weeks ago, I was thinking about writing a book about our walking holiday. Then, at a farmhouse in North Wales, I came across Bob Bibby's Special Offa: Walking the Offa's Dyke Path. I read the chapter on the bit we had just walked, a description of climbing up and down hills on hands and knees in rain and mud.No one could do any better than Bob Bibby, so I ordered this book from Amazon.co.uk...
