Hans Frischeisen(72) is on his 5th non-motorized trek around the world, meaning he travels by bicycle, kayak or simply hikes. In May of 2012 he experienced one of his most demanding adventures riding his bicycle from the city of Manaus on the Amazon River across all of Brazil to the Iguazu water falls. The latter he states, are the most beautiful he has ever seen. He experienced a jaguar, monkeys and an anaconda. What else did he experience in a land with a rapidly expanding economy?
