I rarely see them in Indiana, but hearing them fly overhead while migrating is a joy. Such a distinctive call.

I just discovered there's a map of places to find them: https://sandhillfinder.savingcranes.org/near

In the NW, from the lake down to the Kankakee River, there are a number of state park, national park, and private nature reserve properties that host huge numbers of them. Essentially, what you need is preserved wetlands and they will land. But yeah, that is not the kind of land farmers want to keep around.

I almost mentioned the Jasper-Pulaski FWA. I've visited once or twice during migration season, very impressive.

Depressing, however, just how much smaller the wetlands are now thanks to settlement. Up to 1 million acres lost.
