Who better to travel to some of these incredible places than our own adventuress. Ginger zee. Where are you going now? I get to take you on this journey all week. The first stop. The Platt river in Nebraska. For millions of years, sand hill cranes have used this area as a safe haven. You have to see this story. The symphony of sound. The majestic flight.
