 What, according to Rupert, would be the best place for an alien visitor to observe and learn about humans?
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. You can sit of a sunny morning and read the Paris edition of the New York Herald Tribune while getting your shoes done up like mirrors for thirty Moroccan francs which comes to about five cents at current exchange. Tangier is possibly the most cosmopolitan city in the world. In Tangier you'll find some of the world's poorest and some of the richest. The poorest will try to sell you anything from a shoeshine to their not very lily-white bodies, and the richest will avoid your eyes, afraid you might try to sell them something. As a result of them the permanent population includes smugglers and black-marketeers, fugitives from justice and international con men, espionage and counter-espionage agents, homosexuals, nymphomaniacs, alcoholics, drug addicts, displaced persons, ex-royalty, and subversives of every flavor. Local law limits the activities of few of these. Paul said, "What ever happened to those poxy flying saucers?"
