One of the most enchanting yarns ever uttered on Jamberoo Mountain has been immortalised by an author who wants all to know of Sandy, The Cow Who Came Home.Actor Jack Thompson launched the children's book at the weekend with a reading that transfixed his audience.The launch was at Ben Ricketts Environmental Preserve - the scene of Sandy's fantastic act of devotion.In the book, as in life, Sandy twice finds her way back to the preserve after being sold to a dairy farmer near Mittagong - about 50km away. The preserve was then the farm of Jamberoo Mountain identity Ray Page, whom author and illustrator Penny Osterhaus described as "a kindred soul". Ms Osterhaus learnt of Sandy's journeys during one of many conversations with Mrs Page."When you were with her you felt that she was a very important person, her calmness - she had an enormous capacity for communicating with people," Ms Osterhaus said."I think stories like this tell us something about the human spirit," she said. Thompson's association with the preserve began 40 years ago when his wife, Leona King, introduced him to the holiday destination of her childhood. "What a wonderful place it is - my son's here now and I'm sure my grandchildren will come here," Thompson said. The profits from the first 320-run print copy of the book will go to the preserve.
