They're very good but realize the info in them is only as good as those that put the info in. We had experience here where a man followed the GPS and went on mountain roads in middle of winter. He ended up dying and his wife and children almost died before being found. Also, we've had them give us bad instructions...........follow the instructions but use common sense. And yes, technology is there where they can follow our every move. But I move so slowly and am not a great catch to watch in the restroom, so I'm not worried :mrgreen:
