Reading comments here, I see that some are very naive. I lived there for 16 years. There are many little side roads once one gets off the highway. Those are the smuggling routes.
Like highway stops for drunk drivers, the innocent are inconvenienced so any guilty will be identified.
Some years ago we were checking out the site of the train station scene in “Oklahoma!” (Elgin, AZ, NW of Nogales).
Heading north, we took a two-lane blacktop road and ran into a Border Patrol road check station. The guy took one look at two gray-haired old fuds and waved us through. Told he we were glad to see them out there and got a big grin - probably the only one he gt that day.
Years ago, I remember getting questioned like that at the Buffalo Greyhound depot.
In the last few years I’ve traveled between Quebec and New England several times...via I-89 and I-91 in Vermont.Each time,while traveling south,I’d see the white and green Border Protection vehicles as far as 30 miles from the border.I was never intercepted by them...perhaps because of my Massachusetts plates.
The headline is a lie...... fake news.
The hiways in question were not shut down.
