Loggradbro, nobody is offended or something that you think Utahns talk weird, cuz they do.
The thing is, outside of the Mountain and Layton examples, nobody from Utah talks anything like what you are saying. Like, the Mountain and Layton stuff is cultural, the other stuff is just some random dude you met that talks weird lol.
The pen/pin thing? No bro.
How about creek? Rarely do I hear it pronounced correctly. Instead, everybody goes fishing in the crick.
