Because GPS navigation devices are so common in today's world, compass navigation is becoming more and more of a 'lost art'. Even reading a simple street map is incomprehensible to a lot of people. It's impossible to argue with the convenience of the GPS- they allow us to navigate very precisely with very little effort, which frees us up to enjoy the journey a little more. They also simplify route planning immensely. But what if they fail?... we'd better have a backup!
