I don't have PD, but all my life I have had trouble with directions. I have heard that it actually is a condition. I can get lost in a motel. If I leave a freeway to get gas, often I turn the wrong direction to get back to the freeway. I cannot drive in a large city, because I don't think I could ever find my way back. I have had my husband teach our children directions from their early ages. They can go into our mountain pastures to hunt and always know how to get out. It is very frustrating for me because most people just donot understand. Nancy B cg for Don 64/14
