It's a free service and here I am using it to plan out a five day trip down to Kalispel Montana, Coeur D'Alene Idaho and points beyond.
We may or may not follow the route as planned out but gives us a general idea of where we want to go and how to get there. It also has the the benefit of telling you the mileage and time involved in the journey.
The days of pouring over paper maps is over and one doesn't have to go out and buy the latest in GPS technology to find your way around the world.
