In 1919 the U.S. Army began an epic journey full of challenges; a transcontinental trek traveling on the Lincoln Highway, testing the mobility of military transports traveling long distance. Vehicles often got stuck in the mud, slipped off the road into ditches, and some were even blown over cliffs.

Lieutenant Colonel Dwight D. Eisenhower was the military observer, keeping a daily log of the trip.  Eisenhower wrote,” we were not sure it could be accomplished at all. Nothing of the sort had ever been attempted.”
