On the Iran/Iraq border in Iranian Kurdistan. At 3500 meters altitude in Zagros Mountains. Smugglers move in a steady stream, climbing huge mountains, with 40 kilo weights of flat screen TVs and electronics, from Iraq to Iran, where there are very high duties on these items. See PiPs....first is from whence they climb...the valley below...they are the tiny orange specks, and number 2 shows the scale of the climbs they perfom....not to mention the walk through the valleys below evading border police. We spent a couple of enlightening hours with them.
