The guys at the port in Iquitos who help you carry your bags or cargo (e.g. refrigerators, motocycles, etc.) on or off the boat are known locally as "chaucheros". I originally took this picture to show the boxes of camu-camu fruit (see Camu-camu) coming up the hill. Looking at it now, I am more impressed by the chauchero going down the hill carrying the two 55 gallon drums.
