The drainage water, saturated with iron hydroxides and humic acids, corrodes even a stainless steel. Body is a blood bag permanently subjected to malaria, typhoid, and fungus attacks. Piranhas, electric eels, sting rays and himaras populate rivers and creeks. Thousands of aggressive boars tramp the land. A dangerous bushmaster snake stalks on the land and himaralli snake in the water.
Passengers can only hope for the best.
Where river or creek beds are obstructed by rocks, or dead wood, one must take to trails meandering around fallen trees. Working in such an environment is a daily challenge to one's organization, abilities and determination. The Murphy's Law is at work, gnawing at all plans and time tables. A lack of infrastructure, unqualified work force, and daily difficulties debug managerial skills. Eleven years later, I feel confident.
