Born and mostly raised in California, I have been lucky enough to be surrounded by spectacular motorcycle roads. I often take four day camping-riding treks through the state. I also do not mind a fire road shortcut or side adventure when on a big trailee. By far and away the Devil's backbone is the most jaw dropping, heart pounding, thrill around every bend, road I have had the pleasure to roll over. There is a section of highway 160? in Missouri toward Arkansas that was great and the is the Pig's Tail in Arkansas that ranks way up too.
If I am near Durango or Mazatlan, I will not pass up the thrill of riding up the Devil's Spine. The town of ElSalto is in between and a great stop over.
The road in the picture reminds me of Pikes Peak. I say after a while a back and forth switchback tends to get a bit boring. I like a hill and dale ride.
