A 20-year-old mare named Sadie was shot to put her out of her misery after a bloody 200-foot fall down a mountainside. But the real-life horse opera had a happy ending when the tough old thoroughbred overcame the accident and the bullet in her head, and she went home after a month in the wilderness. Sadie slipped on a trail and rolled down the steep slope during a pack trip to Jupiter Lake in mid-September with owner Janet Boling of Brinnon, Wash., her husband, Steve Boling, and a son. "She was cut everywhere and bleeding. Her left eye was swollen shut. We decided it was best to put her down," Janet Boling said, and a friend who hiked to the horse with her shot Sadie. About a week later, the Forest Service contacted her with reports of a horse wandering in the area, but it took about two weeks more, and a hiker's description, to convince her that it was Sadie. Finally, on Oct. 11, a rented helicopter flew Sadie home. Janet Boling said a veterinarian pronounced Sadie in good health except for weight loss, a swollen left knee and blindness in her left eye. Sadie has packed in her packing days and will now be just a pet for the Boling children, Philip, 7, Adam, 6, Jason, 4, and Melissa, 2.
