LOL!! GPS is science, not magic. Hence, it screws up from time to time. It really does still help to be able to read a map and have one.
wonder if there is a plan by the feds to kill the accuracy in times of emergency?
I remember the time when the accuracy was very poor; by design. Clinton had the feds turn off the intentional error and the rest is history. It made a marginally functional consumer product very useful.
