Cities smell. This is normal. And...
Each has its own scent. Just like the legendary Russian novelist, Leo Tolstoy, wrote at the beginning of “Anna Karenina” (a novel published 1873). “All happy families are alike, but each unhappy family is unhappy in its own way.”
Mkokoteni pusher - Magomeni, Dar es Salaam, 2009.First time I arrived in Dar es Salaam in 1970, aged fifteen, I recall the smell of the sea salt and water. Nothing else. These days Dar stinks of dust, smoke and car fumes. The sea salt and fish can only be found closer to the beaches of Kigamboni, Jangwani, Kunduchi, etc. These palm trees (below) are hard to find in the mid city today.
City smells tell you something about inhabitants and their activities. When I first set foot in Copenhagen in 1984 I recall the pleasant aroma of bread, cakes and alcohol.
