Not so much a straight road, but a where does it go question? This trail is in the high mountains of southern Wyoming with nothing around it. As a kid I recall seeing this when I was learning to drive a 4x4 pickup when I was 14. It was spring and very muddy, and what little advice my dad gave me about driving was, "Son, you get a 4x4 stuck out here and you've got a problem." Many years later I drove back here to find out where it went.
Trail into the sky with a nice drop off to the right.
