It was the spring of 1848. Almost 400 wagons, each with a plow fastened on its tailboard were gathered at Kansas City, the jumping-off point on the long overland trail to Oregon. They had come from all over - some as far as 1,000 miles. Now they eagerly awaited the arrival of the last contingent of wagons from Liberty, for there were 2,000 miles to travel before snow covered the distant mountain passes.
