Hunters who come out there from back East, where open-country shots are less common, gawk at a buck on the sprawling plains and think he's a mile away. As a result, they aim for his spine or even hold a hair above it. "A deer is usually closer than you think," says the guide, who urges his hunters to hold low on an animal's chest. "I whisper over and over, 'Aim for the heart, aim for the heart.' It helps keep them focused."
