Nebraska is where Midwest meets West, literally. Geographers identify the 100th meridian, which nearly halves the state, as the boundary between the two regions. But travelers don't need a sign to recognize the divide. As in frontier days, the majority of Cornhuskers live in the state's eastern half, and out west, the sun still sets over vast grasslands and yucca-capped buttes.

From late February to early April, 500,000 migrating sandhill cranes feed and rest along the Platte River in the center of the state near Kearney.

The northbound cranes present one of the planet's great remaining migrations. And thanks to viewing areas stretching along Interstate-80 from Kearney to Grand Island, you can see the birds with hardly more effort than it takes to pull over for a cup of coffee. outdoornebraska.ne.gov
