We can see Boquillas Del Carmen, a village across the border, i.e. across the Rio Grande. Stashes of hand-made walking-sticks and copper-wire figurines are tucked along trails and overlooks. The cardboard signs request money to bus the children of Boquillas to school. Buying such “contraband” is explicitely stated as illegal by the park service and federal government. Tourists can visit Boquillas through Big Bend with a passport.
