In a recently unknown land, roads are rapidly being built by volunteers. There is no construction experience required, and seasoned road builders keep a watchful eye. Exits are abundant, offering frontage roads, detours, and highways to far away places. It is truly a revolutionary system of transportation.
The roads provide utility that the citizens of this land now rely on. However, some also use the roads for sport, racing each other to exotic destinations. With myriad paths to the finish, each racer must anticipate future exits and above all, never backtrack.
The roads also have a unique quality which can be easily demonstrated. When asked how to get to the capital city, most locals will respond with a grin, "Just keep turning!"
