Back in the days before cell phones were common my car broke down on a lonely stretch of highway in Michigan. It was very late at night. I sat there for 20 minutes and no other cars passed me. I decided to write a note as to the direction I was walking so that the search parties would have a good chance of finding my unconscious body. Just as I finished writing the note a tow truck stopped to help me. I always felt lucky that the first person to stop was someone that could genuinely help.
