Zipping to School

German explorer Alexander von Humboldt was the first Westerner to observe the unusual rope system in 1804. Back then the ropes were made from hemp, which has a propensity for breaking due to rot. The hemp ropes have since been replaced by steel cables. What hasn't changed is that they are 1,300 ft above the river, people zip down them using only a small stick to control their speed and if you are too small, you have to ride in a burlap sack (video).
