US191 in Arizona is one of the most challenging paved rides I know of. I rode it in March. A complete ride report is at: http://www.tomfranken.com/Pictures/US191/us191report.htm.

A couple of scenery shots. This is from the Blue Vista overlook. (Note to RM's: this would be a great boni!)
A panoramic..
The temps were in the 60's. Imagine walking across that in the 100's.
And yours truly taking a break.
The signs tell the story. The little one up ahead mentions something about ice.
If 20 is too fast, we can slow down.
Or maybe slow down some more!
Should you go in too hot, you'll have a long tumble. Note the lack of guardrails!
The town that marks the turn-off is Three Way. Blink, you'll miss it.
