Sunrise over the Ruta Nacional 7, an east-west directional highway that cuts across South America, joining Buenos Aires, Argentina and Santiago, Chile. Such a scene is very common on Argentine highways; you're almost guaranteed to see at least one if you're on a road trip, hitch-hiking trip, or if you do medium to long distance driving for a living.
I caught the sunrise at about 8am on a summer day, travelling west. The irritating thing about hitch-hiking towards the west is that you get the sun in your face in the morning. And if you're travelling towards the east, you get a fiercer afternoon sun in your face.
