Expedition in Uganda, Julian Monroe Fisher
In the mountains you could actually drink the water right out of the streams. However, once we dropped down from altitude we were in locations where there were no villages or bottled water so we had to rely on our SteriPENs for purifying all water. The porter responsible for water was our cook, Cornilious. He became quite proficient in the task of purifying water. Halfway through the journey, which was the toughest trek I have ever been on, we managed a night back in the town of Fort Portal. That was the only night we did not purify the water since we were based at a local hotel. I paid the price by getting a stomach problem that stayed with me until I returned to Austria. I plan to never again travel without my SteriPEN!
