Start briskly!

This small guide contains everything you need to know to locate on a map, and thus to organize its hiking.
It is educational, explains everything from different cards (s leu and legends with the usual conventions) it helps to learn to use a compass.
Exercises are used to verify that the concepts taught were acquired. Would recommend to any backpacker who does not wish to engage in random and end up lost. In so few pages it's perfect!
