I was involved in a crash last weekend (I'm okay - just some bruised ribs and scrapes, and a destroyed helmet but I'll be okay for my trip to Colorado in a week!) and another woman who also went down didn't have any id on her. She hit her head too, but she had no memory of her name, where she was, or what she was doing sitting on the side of the road...
