La Mujer Roja

Strolling seated on the capó of a car, the Red Woman is trainspotted against her will across the Unitedstatean desert of Chamical:
at night, the car is surrounded by saltimbanques and degenerate weird cohort of chitrulos

does someone really know her color?

Red, magenta, crimson, pink, purple, solferino, rosa sucio?

Where does she go? Who's driving?

Hard to guess.

Apparently she's going to the north, to Vergas Nevadas, although the direction could shift drastically, depending on the angle of the orticón.

This is the never ending story of a Red Woman who journeys forever, over the Unitedstatean deserts, and she journeys en pelota picada

... but is she red, or pimpernel? 

Escarlata maybe?
