The call for a wall along our border with Mexico has a long history. In fact, the first border wall was built 100 years ago… it was a 6 foot tall fence that went straight through the town of Nogales, Arizona.

Walls and fences represent a very human impulse: to have an actual physical barrier that marks the imaginary one on the map.

It’s a simple idea. And – like most things – it turns out to not be so simple.

Today on the podcast: stories about walls and borders, and what happens when – instead of people crossing the border – the border crosses the people.
