Our GPS routed us on a bizarre routing on a two lane country road after leaving Amarillo, Texas, for 20+ miles through oil country to Channing and then north. Unfortunately we were running on fumes and if there was no gas available in Channing we would be stranded. As luck would have it, a local diner had a gas tank and station and we were able to fill up because it was quite a distance up the road to the next town.
