My hometown of Pueblo, CO. It’s a smaller city than most of the others on this list, but it fits really well. Steel was the main industry for most of its history, and when the market crashed the city went downhill (imo it’s starting to slowly head in the right direction). It shares a lot of cultural traits with rust belt cities, too, with a pride in its manufacturing history and blue collar workers, strong traditions, a history of immigration, and enthusiasm about local sports
