map misunderstandings

I was watching the 'reality show' the amazing race this evening. I love the scenery but cringe, sometimes at the lack of knowledge of the contestants. Of curse it might just be the pressure of the moment. They do seem to do a lot of running around. What made me wondrr about their map skills this evening was when one young lady pointed out to her partnerthat way was morth because she was holding a mao and the little arrow on the map was labled north. Her partner tried to point out that if she continued holding the map but turned around north would be in the opposite direction. He then tried to explain to her how a compass works, although he didn't seem to clear on that concept. Perhaps we should blame this directional disfunction on GPS systems. If you have a little voice that tells you "Turn right' turn left." you really don't need to know  north and south unless the system fails.  Is that what happened to our ship, reportedly on the way to North Korea, that ended up off the coast of Australia?
