Authorities hint that a drug-running tunnel – the second discovered this month – was a major conduit into the US from Mexico. It's the latest indication that border security is driving smugglers underground, literally.

If you can't beat them, tunnel under them.
That seems to be one credo of Mexican drug smugglers employing prairie-dog methods to build sophisticated tunnel systems that allow them to carry tons of marijuana into the US.
The discovery over Thanksgiving of a half-mile-long drug tunnel from a house in Tijuana to two warehouses in San Diego's Otay Mesa community, marks the second such find in less than a month. A tunnel the length of six football fields was found Nov. 2, also from Tijuana into the San Diego area.
Both tunnels, US authorities say, came complete with light-gauge rail lines and rail sleds powered by car batteries, to more quickly move bundles of pot as deep as 70 feet below the borderlands. Some tunnels – including the most recent ones found – show very sophisticated engineering, sporting ventilation, lighting, and even drainage systems.
