Perhaps you're planning a trip. The river has washed part of it away. I will show you the detour. Ignoring our little Samaritan's offer, we drove on.
Sand dunes occupy only a fraction of the Saharan landscape.
Terrain is mostly rocky plain. Like rain in London or messy hotdogs in New York, hustling is an integral part of Morocco's local color. If you feel picked on, remember that Moroccans themselves get hustled all the time. Although authorities in major cities have been successful in curtailing harassment of visitors, the country's soaring unemployment rate and the widespread perception that all tourists are rich will probably ensure that hustling and price gouging remain constant factors in traveling there. Remain polite but dismissive when people approach you to offer unasked-for services or aggressively try to engage your attention.
