Drug Smugglers Burrowing Under the Border

US aircraft drones patrol the skies, while border police guard the land routes. It's hard these days to get your drug payload into the United States! What's a smuggler to do? Apparently, they've returned to the golden days of smuggling via tunnel. On Thursday, police discovered the first underground tunnel, right under the checkpoint in Nogales. Before they could even get the first tunnel filled, in they found a second one a block away. Both tunnels led to a storm drain on the opposite side of the border. It's still unsure if there are other tunnels, but both will be filled in to prevent use by drug and people smugglers.
