Just a tidbit here.
I'm taking my wife as an example - but not picking on her :-)
She tends to be a person who has always had some trouble with navigation. Some people just do - their brains seem a bit less connected to memorizing landmarks and noting directions. However, she really made major progress once these automatic GPS devices, along with route guidance, became available. She has relied on them ever since, and really could not get to a lot of places without them. I suspect my wife is part of a big majority of people who drive, and sometimes hike, relying highly upon GPS. To the people on this forum that may seem like madness .... but that is the modern world that we live in. It is - what it is. If for some reason all the world's GPS signals came to an abrupt end ... there would be a LOT of people stranded out there. A lot of folks don't even carry hard-copy maps anymore.
