Completely missing the Pittsburgh accent which is quite distinct. But I don’t think I’ve ever seen it depicted in TV or movies either so it’s likely that most Americans are completely unfamiliar with it.

I wouldn’t say most Coloradans have a Midwestern accent either, especially in the front range.

Edit: it’s even hard to find good examples on YouTube. Here’s one guy but I would say this is just one type of accent and it’s not that strong. You should hear my cousins…
