"In your car: have a permanent marker in the cup holder, glove box or between the front seat pocket. If anything happens, you see anything, need to remember something, write it on the glass window, rearview mirror, on your hand, anywhere. Pens & pencils are unreliable. Clean off marker later. (For a license plate #, address, car make, model & color.)"
