In 1972 I was 23, I had car trouble on I-5 in Seattle Wa. I pulled over to the shoulder and since it was 3am I decided to sleep in the back seat until daylight. I was fast asleep and heard a tapping sound, I woke up to a flashlite shinning in my face and a voice said what are you doing here? I told the State trooper my problem and he said it was not a good idea to sleep in a parked car on this busy freeway (speed limit then was 70) so he gave me a ride to the next exit and so I could call someone for help. When I got back to where my car was it was gone. I found out my car was at the tow yard, when I got there they showed me my car and I almost fainted, someone had fallen asleep on the freeway doing 70 and rear ended my car. I never did find out that trooper's name but that night he saved my life.
