Then there are those of us who had to learn land nav with map and compass. Warn't no GPS way back when. Why I tell you, we had to magnitize needles and float them in a puddle on a leave to determine north (actually works). The worst part was when the dinosaurs would step on your leave...

As previously stated, I learned land nav as a Scout. Then once I joined the service, the first NCO school had a fearsome Land Nav course with one heckova mean evil and nasty written test - mixing map degrees and magnetic and if you didn't notice -- ahhhh. And you had to be on a spot to 8 digits. Better have a sharp pencil, as a dull one could cover 50 meters.

GPS is simple, if you can read and understand a map it is a great tool. But once the batteries die, whatcha gonna do then?
