I am very fond of using GPS navigation and it’s one of the awesome application that has been truly serving to the mankind of 20th century. I feel handicapped without it, however there are times when this smart fellow confuses us. It will lead you on the path which is either one way or still under construction. Sometimes it takes you thru the shortest route and then you realize that the road is lonesome and then you do nothing but bite your nails in a hope that this is the correct road. So do take special care if you are traveling at night and confirm the road before you take that left or right turn. There is nothing wrong in asking for the direction to people.
