I found this youtube video to be extremely interesting especially after learning about the blind baseball team. Just like the baseball team Daniel Kish also uses sound to be able ride his bike. He can use the sounds to tell when a car is coming or ever when he is suppose to turn. Daniel makes clicking sounds as he rides his bike as if he is own form of echo location so he can hear the sound bouncing off objects. Even when he is walking he uses his clicking sounds to hear it bounce off locations and he can tell where things are. With that sounds he can tell where buildings are, cars, poles, etc. Daniel clicking sounds are his own human sonar and he is now able to live a everyday life without anyone else help.
