Borderlands

This week, two stories from the U.S. borders. The first, from Javier Zamora, who crossed into the U.S. without his parents when he was nine years old. The other comes from our border with Canada, which Porter Fox navigated from end to end, by canoe, freighter, and rental car, encountering an increasingly policed border, Native American uprisings, and the unmistakable impact of climate change.
