I followed a GPS once in eastern Pa. I knew it was heading me wrong but I wanted to see where I would end up. No lie, it took me to a cornfield near New Hope Pa.
Some friends came in from out of town, and they wanted to out to eat, so they punched it is to the their GPS (on a phone) and it took us the wrong way. I too was curious to see where it woudl take us. I took us to a suburb not quite out into the sticks, but bordering on it. I suggested they plug in the movie theater next door tot he pub and suddenly the GPS knew where to takie us.
No kidding! It sent me to a dead end, I swear I heard banjo music.
Just wait if we ever go to a major war and they shut down military satellites. Nobody will be able to go anywhere.
