Once upon a time we experienced a highway that ran from Alpine and Clifton in Arizona.  The highway designation, Route 666.  The road is known to be challenging as it has elevations ranging form 1,600 feet to 11,000 feet which is almost the elevation in Estes Park, Colorado,  One traveler counted 1,100 curves in 95 miles.  The weather can be cold in the higher elevations and its been said that it actually snowed in July.  It's also beautiful and it has it share of wild creatures that you don't see in the Valley like the wild Turkey.

Travel writer James T. Yenckel, in an article in The Washington Post on December 29, 1991, commented:

The verdant countryside, abloom in summer wildflowers, is largely untouched, and it must look now as it did centuries ago. The route was a struggle for me.. An almost empty highway to nowhere, U.S. 666 climbs to above 9,000 feet along the Coronado Trail in a cliff-hanging series of twists and turns so sharp the speed limit often drops to only 10 miles per hour. The reward for this little test of nerves is a picture-postcard panorama of pine-draped ridges leap-frogging across the horizon.

Route 666 was established in the 1930's and began at Douglas on the Mexican border. It went north and then east near old route 66 and ended at Lupton, AZ near the New Mexico border. In 1992, the route number was changed to U. S. 191 supposedly because north-south routes were not supposed to have even numbers. There are many who think the change was for different reasons such as the superstition and fear behind the number "666."

There were those who believed that 666 was the "number of the beast" (or the Antichrist) in the Bible and so the road acquired the name "The Devil's Highway. The challenge of the highway brought more than its fair share of traffic accident the perpetuated the name.

The fears and superstitions centered around the name of Route 666 brought about a name change in 1992.  The new name was to be known as U.S. 191 in Arizona.

Isn't is amazing what speculation, innuendo, and superstition can accomplish.
