Roads of the Dead
I’m going to Spaceport America. To access the spaceport, I’ll have to cross the Jornada del Muerto, a desert basin cut by a hundred-mile road. I calculate and the Jornada del Muerto is longer than the distance between the edge of space and my body on land. Trace one expanse, maybe you’d carve across another. The Jornada has been mapped many times, including by Google.
