For almost 2,000 miles, one line defines a country and divides the world. What is life like at the U.S.-Mexico border now, and how would a wall change that? In this podcast, journalists take you with them to the border to find out. Meet a human smuggler. Ride with armed vigilantes. Get bitten – lightly! – by a jaguar. Fly over the entire border line. Hear what journalists go through to get these stories – and the surprising things they learn along the way.This podcast is hosted by Nicole Carroll, executive editor of The Arizona Republic and azcentral.com, part of the USA TODAY NETWORK.
