EXPORT, Pennsylvania After logging several thousand miles driving along the back roads of the United States most of them numbered U.S. highways and state roads, but also some dirt roads that I wasn’t quite sure were even supposed to be actual roads I pulled up to a Sheetz gas station. Once again, I was to fill up a tank that had been depleted many times over in those two weeks. Both parenthood and the nature of my job taught me to always go home with a full tank of gas.
