27 May 2023, and day 8 of my 21 day motorcycle trip across the US. The Devil's Highway in Arizona was one of my very favorite parts of that trip. The ride was several hours of pure joy. My GoPro batteries died about half way, but hopefully you can still get the gist. US 191 (Formerly US 666) has my vote for the best motorcycle road in the United States. Add it to your list and you will not be disappointed. I rode from Alpine Arizona down to the Copper Mine at the south end... and it was fantastic. I continued on to Payson Arizona the same day. Awesome day of riding on my 2023 Triumph Tiger 1200 Rally Pro
