In the old coastal town of Lamu, Kenya that is inundated by donkeys, you get a rough idea of what a town full of horses and fish smells like. The air is filled with an almost oppressive smell of poop and fish. It is unquestionably unpleasant. In some other towns, you are reminded of the smell of exhaust from old trucks belching pollution into the air. And lest you forget, you'll be reminded of a modern western construct - deodorant.
