From NASA/JPL Mars Photo PIA16128 . Anyone who has worked in the "Oil Patch", would immediately recognize this as a "mini-crane" or "Drott" by brand name - often used to pull-out massive pumps for repairs. This Martian version appears to be driving away with the "boom" slightly raised. That may be the "wrecking ball" swinging left or a "driver" in white with dark hair. Any Ideas?
