Souks, ancient markets of the near east. Noisy, funny smells and crowds. They seem to trade everything from spices to silks to slaves! At least they used to. In the Sahara, the Berbers were notorious for their pillaging the caravan trade that traverse the desert all the way to Timbuktu (it really exists in Mali, look it up) in the old days.
Today while many Berbers are settled, the souks that they gather to trade remains. By the way the featured image shows how an open souk trading horses and camels look like. Be careful not to lose your wife in the maze of the souk.
