I grew up in central Montana but now live on the west coast too, and I’m astonished at how quickly it’s changing. The bellwether for me is the fact that stream access law* is being challenged (most notably by Gianforte and other wealthy, often absentee landowners). If public stream access is lost, I’ll know the state and it’s civic makeup has changed irreversibly. *Everything below the high water mark is publicly accessible per Montana state law.
