On the snowy border between New York and Canada, the local sheriff’s office is calling for the U.S. Border Patrol to put more manpower behind what the locals call a growing crisis: The number of illegal border crossings in the area over the last five months is nearly 10 times what it was over the same time last year, and the border crossers are in danger of freezing to death. From Oct. 1 to Feb. 28, about 2,000 migrants crossed the border between Canada and New Hampshire, Vermont and New York south through the forests, compared to just 200 crossings in the same period the previous year.
