Los
Ebanos, in South Texas, is the last hand-pulled ferry to cross the Rio
Grande River.


Where the Rio Grande River makes a bend in El Paso, the international border
fences are clearly visible. The bed of the Rio Grande has been
cemented to control the water flow and to fix the location of the river as part
of the solution to the international border dispute. On the United
States side, a over-hanging curbed wire-fence runs next to the river,
then a dirt surveillance road, then an outward-facing (towards Mexico)
angled-wire fence, another dirt road, and another outward-facing
(towards the USA) angled-wire fence. Some of the wire fences are
electrified
with warning signs. Electric lights and electronic surveillance
(cameras) towers periodically run parallel to the fence. Check out the
border in San Diego, CA.
