In the mid-nineteenth century thousands of Americans took a wide variety of farm wagons across the Great Plains from developed parts of the Midwest to places in the West. Overland migrants typically fitted any sturdy wagon with five or six wooden or metal bows that arched high over the bed. Over this was stretched canvas or similar sturdy cloth, creating the distinctive covered wagon silhouette.
With MOGA 2017 heading west many have hooked up their current version of their covered wagon way out west.
