One of my cycling friends broke his ankle when he fell off a stool changing a light bulb. His foot is in a cast and he is going nuts because he can't ride. He told me today that he plans on riding with his good foot in clipless shoes (so he can pedal a full rotation) and he will suspend his cast leg from the handlebars with a bungie cord.
I told him he would kill himself especially when he tries to stop. He feels confident that he can unclip and use his dominant foot for support. If he leans the other way, I know it is curtains for him.
You probably will be reading about him in the papers if I can't convince him otherwise.
