I did something similar lately. But it's hard to keep up with local news, now. I couldn't find a news aggregator for my country/province. Maybe, I need to build that myself.
I recently started reinvesting in RSS via reader that I can sync, and was pleased to remember that my local paper (a Gannett paper, which matters since they use the same engine on all their properties) supports several RSS feeds, from a site-wide news feed to counties or topics. It's been good enough for me to not push further, but I imagine my local TV news sites have similar feeds. This should scale up from county to city and state, I'd think.
I went through an "unfollowed" everyone in my feed except very close family and friends, the local farmers market, and my local newspaper. Facebook is actually useful now.
Some people don't believe it when I say this, but when I unfollowed lots of people, after some time Facebook just automatically re-follows a few.
It has happened multiple times. I explicitly unfollow someone, never interact with them in any way, and then they again pop up in my feed after two weeks. Somehow if you follow too few people, Facebook just picks some more people for you to follow without ever asking you or telling you.
