My best bud and main hunting partner had his right arm amputated due to bone cancer. He not only found a way to get into the woods, but he likely wouldn't be here today if it wasn't for his desire to be in the woods. Not only is he hunting, but he has found a way to win 2x world championships, and countless state titles as well shooting his bow.

If he found a way to do it with one arm, your Dad can find a way to do it with one leg. Show these pics to your Dad, hopefully it will get the fires of desire good and hot for him. I wish him the best of luck, and hope the both of you have many more days afield in front of you.
