Hello, and welcome to a special edition of the NewsHour podcast, the first of two bonus editions, no less, ahead of the US Presidential election.
This one is coming to you from San Antonio in southern Texas on a beautifully warm morning.
Now, this feels like a city that's going places.
We're recording this in what's known as the Pearl, a small downtown district of newly restored old buildings and some new units, mostly given over to shopping, restaurants and coffee bars.
And even at this time, it is filling up with people enjoying the sunshine.
Now, San Antonio is just a couple of hours drive from the border with Mexico, and that influence is everywhere.
Spanish is widely spoken.
Two thirds of the population identify as Hispanic.
Many people have extended family in Mexico.
And there is plenty of movement to and fro people and goods.
The two subjects we're going to talk about today, because that journey across the border is one we've made over the past couple of weeks.
From Mexico's commercial hub, Monterrey, to the Texan border town of Laredo, through the cattle ranches just north of the border and then onto San Antonio.
Well, let me introduce my guests here today.
