CÚCUTA, Colombia (BP) -- When Nelson Martínez' father died this summer, Martínez inherited a piece of property half a day up the mountain from his hometown of Cúcuta, Colombia. The property sits at 10,000 feet at the top of a cold, often rainy mountain pass. Every day several hundred ill-prepared Venezuelans walk over it on their way to try to find food, work and medicine in a new land.
Some have died of hypothermia. All are desperate.
