Archery can be a difficult sport, especially with huge obstacles. People use a variety of techniques to make it work for them. Jeff Fabry uses a very different technique than most. He was injured in a motorcycle accident when he was 15 years old, losing an arm and leg. His friends would go out to hunt, and he was not able to join them. Some people would give up, but not Jeff.
Jeff designed a mouthpiece so that he could use his mouth to draw back the bow. It was all trial and error, but he found a way to make it work for him. He designed the mouthpiece from a nylon dog leash.
