Sorry, your own extremely biased observation doesn't establish the truthfulness of your comment. SuperTank is spot on, it's a really ridiculous comment. BTW, I live in Utah, but was born in CA and lived my formative years in AZ.

Your "supporting evidence" was also pretty bizarre: how does the inability to properly use "than" vs "then" relate here? Are you just going for a "People from Utah are dumb" approach? It's a pretty silly argument, if true, and doesn't match up with my experience either. While I certainly see the grammatical failings here, I've seen them from people everywhere. I think you're seeing what you want to see, rather than making an objective observation.
