Touring Rockies' rural highway US-40: Rabbit Ears, Colorado to Duchesne, Utah

US-40 runs from Denver, Colorado to Salt Lake City, Utah and is well-known for being the double-tankers haven. It should be also known that US-40 is a tough nugget to crack for inexperienced drivers as it is a two-way highway with very slim shoulders, plenty of inclines and declines. During winter, you could still see crazy King Sooper's tucks climbing the 12,000 ft elevation near Winter Park.
