A desire path (often referred to as desire line in transportation planning, and also known as a game trail, social trail, herd path, cow path, goat track, pig trail, use trail or bootleg trail) is a path created as a consequence of erosion caused by human or animal foot-fall traffic. The path usually represents the shortest or most easily navigated route between an origin and destination. Width and erosion severity can be indicators of how much traffic a path receives. Desire paths emerge as shortcuts where constructed ways take a circuitous route, have gaps, or are non-existent.······
