In recent years, a family road trip might present a few new challenges like managing fuel costs and attention spans. But at least navigating on the road is a pretty straightforward experience with a smartphone: punch in the address of your destination, hit “start”, then be on your way and simply follow the steps as you go. However, for those born sometime between the interstate highway system and satellite navigation, things weren’t so simple. Someone in the family would often be a designated “navigator”, whose responsibility was to read huge, unwieldy folding paper maps covered with different color-coded lines, symbols and names, all the while telling the driver where to turn next without losing track of the route to their destination.
