Treasue County, Montana is another example
There is only 3 towns in the county and the only incorporated one (Hysham) lost its cable franchise recently (within the last year). Mid-Rivers pulled out of there.
what is weird is looking at the public files for Mid-Rivers they said the franchise was sold March 2015 yet I cant find any info on who bought it. Their FCC file just says "deleted":

but their main page says "Hysham (system sold 3/1/15)"
