One evening a friend of a friend called. She needed my help, so I agreed to drive to her house.Although i had a map in the car, I decided to use the GPS to find her town. It was dark, and i wanted to get there as quickly as possible. Everything was going fine. I was almost there, but then Suddenly I saw there was a small river on the left. I could see that there was road that went through the water to the other side of the river. the gps said ‘turn left'
