I continued on Route 6 into the center of Denver to the Arts Museum area which is beautiful but with no Route 6 signage and my GPS trying to return me the way I came into the city, it was a hazard to try and read the AAA city map with the weather conditions, so I finally gave up and GPS'd my way to one of the target suburbs on the U.S. Route 6 Route. With Route 6 sharing the road with several other U.S & CO State Routes and Interstates, Garmin GPS directions hardly ever recognize Route 6 as the Alpha Route.
Out of the Denver metro area Route 6 finally takes off on its own above Fort Morgan in Brush, CO and it was such a relief getting off those double barreled freeways and enjoying the feel and low volume traffic that the two lane Route 6 has to offer. I also outran the rain that was plaguing the Denver area and Rockies. The speed limit on the Colorado freeways is either 70 or 75 mph while the two lane roads are 65 mph so you don't really lose much time. I have been averaging 18 - 18.5 mph with the Tundra depending on mountain terrain or flat prairie which was a pleasant surprise for this 5.7L V8 power plant, but the truck will cruise 75 mph at 2000 rpm in 6th gear.
The terrain in northeast Colorado also changed to flat farming and cattle country that continued into Nebraska. There were two large Black Angus feed lots with over a thousand cattle in each of them along Route 6, one in Colorado and one in Nebraska; I could smell them before I saw them.
The BNSF train line runs along Route 6 for most of the drive and there were long coal trains every 20 minutes traveling into Denver from the Sterling area with empty coal car trains heading back east and north to the Powder River Basin of Wyoming and Montana. You do get a sense of how important coal for power generation is in the West. Every 3rd or 4th train was hauling loaded grain cars and the 18 wheelers on Route 6 heading toward Denver were hauling cattle. I have also developed a strong respect for the American farmer and how much they are the backbone of the American economy. In addition to providing all our food, farmers provide the economic fabric for much of the land that both U.S. Routes 20 & 6 cross.
After losing an hour's driving time somewhere in Nebraska, I found a room in the town of McCook, NE for the night.
