I’m not crazy about Wired magazine. The type is too small and the content too nerdy. But the February 2011 issue is fascinating. The cover stories on “The Underworld Exposed” feature pieces on dark-side subjects ranging from selling body parts (“How to Buy a Kidney”) to how underground caverns keep things ranging from Kraft cheese to WikiLeaks cables cold and safe (“Beneath the Surface”) to a guide to “Uncommon Underwear” such as “Smuggling Duds” and “Blast Boxers.” Also study the great map showing “A Flow of Transnational Organized Crime.” It looks like a map of the Boston subway, but the green line marks the route of cocaine smuggling, the red line heroin, the orange line firearms, the blue line counterfeit goods, the purple line female trafficking and so on.
