It was dark, it was snowing, hard and accumulations were in excess of a foot. A snow plow driver noticed a car that had been following him for 20 minutes. No matter how or where he turned the car stayed right behind him. Finally, he got out and walked over to the car. The driver, a young woman around 22 years old, rolled down the window. “Hi,” she said.

“Hello. Why are you following me?” The snow plow driver asked.

“Well, my dad always told me if it’s snowing really bad just follow a snow plow and you’ll never get stuck.”

The driver thought for a minute then said, “That’s pretty good advice but I just need to tell you that when I finish doing this parking lot I’ll be going across the street to do that one.”
