Hi Carrie: I sustained a head injury in Virginia during a drag hunt when my horse balked at a gate and I flew over his head. I did get a concussion but fortunately broke no vertebrae as Christopher Reeves did in a similar accident recently. My heart goes out to him. I also had abortive Polio at about age five. There is a book written by a PD victim called FORCEPS VICTIM byCorinne Baker Jaillet who lives in Bouctouche New Brunswick. Barbara Yacos
