Okay we get it, some northern Michigan locations don't have much of a population. A little hamlet like Toivola can claim a post office if not much else, but its USPS outpost looks like little more than a tiny house cut in half.
If you get your mail at the Elm Hall Post Office, you better hope no one else is there when you stop by, there's likely not room for both of you to be inside. This is the smallest post office in Michigan.
