If you live in Montana, chances are exceedingly small that you're going to find anyone netcasting your locals (legal or otherwise). Of course "local" in Montana has a different meaning than it does in most other states as some of the markets cover a lot of acreage.
Have you checked out Fubo? I live in South Dakota and it's tough to find streaming services that offer my locals as well. Hulu has all 4. Fubo has 3, just missing ABC. And Vue has Fox and ABC. The rest don't have any of them.
