Yes, you should plan a trip next spring to this wonder of the world. The Sandhill Crane migration is the largest in the world and well worth your time. Your sense of adventure will rise to a new height as you marvel at these birds. Fly, take a bus, drive, get there any way that you can to witness this extraordinary event. We planned to spend two nights there so we could be certain to witness one sunrise and one sunset. We did not book any special tours or bird blinds and yet we saw plenty.
If I had not seen them in New Mexico I likely would have missed them in the fields at first.

Here is a very short clip

Here is a clip from Geographic.

This video is phenomenal. Yes, 8 minutes long, but their photography captures what I could not. Even Bob was challenged in the low light conditions of sunrise and sunset along with the skittishness of the birds themselves! We supported the Sandhill Trust while we were there.

Then off to Cheyenne Wyoming, 338 miles away. As we drove through Nebraska along the Platte River we saw fields with birds, and then more birds!
