 What is Paul doing in Tangier?
One can't be too cautious about the people one meets in Tangier. The Place de France is the town's hub. It marks the end of Boulevard Pasteur, the main drag of the westernized part of the city, and the beginning of Rue de la Liberté, which leads down to the Grand Socco and the medina. It's quite a town, Tangier. King-size sidewalk cafes occupy three of the strategic corners on the Place de France. Tangier is possibly the most cosmopolitan city in the world. In native costume you'll see Berber and Rif, Arab and Blue Man, and occasionally a Senegalese from further south. In Tangier you'll find some of the world's poorest and some of the richest.
