You'll find, while walking through certain parts of the markets of
Bahir Dar, that everyone is sneezing and coughing. Than you begin to

...chili dust. Millions of fresh and dried chlil peppers being thrown
around, crushed, threshed and sorted. Good Luck.

Taken in the market of Bahir Dar, capital of the Amhara Region, Ethiopia.
