If you haven't spent much time in the southwest, you may not know about this, but there are these border patrol checkpoints that are just in the middle of interstate highways and other roads... not at the border. They're as far as a hundred miles away. Reporter Debbie Nathan used to go through these checkpoints regularly when she lived in El Paso in the '80s and '90s. But not long ago, she discovered something that made her see the checkpoints in a whole new way.
Debbie Nathan did another version of this story which broadcast on Latino USA. (25 minutes)
