Great points, especially #6 - cross reference to the current thread on the lost hiker in the Gila Wilderness, where map reading skills were a part of the problem.

People seem to think that GPS supplants map and compass; useful as it is, it supplements M&C. If you can't interpret a paper map, how can you interpret one displayed on a screen? - that will disappear when the batteries expire? - that can't receive a strong signal? etc.
