Leg wraps are like ace bandages only better.
They make it easy to create a makeshift splint too. I know it has been a long time since private pilot training but this could actually be the thing that saves your life. If you do put it in a field and don't actually see a place to make a phone call make certain that your ELT actuated. They don't always go off by themselves. OK, you are warm and dry.
