Fernando del Valle reports:
Near the banks of the Rio Grande, U.S. Border Patrol agents monitor a tethered balloon that carries a camera that can zoom in on a license plate miles away.
On a ranch off Peñitas’ South Main Street, the 55-foot-long surveillance balloon, called an aerostat, arrived as Army surplus from America’s conflicts in the Middle East. It rises like a blimp from this tiny farm town less than a mile from the U.S.-Mexico border.
