Thrillist has figured out how to map the most popular hamburger in every county in the U.S. based on Foursquare check-ins:

And what, you ask, is number one in (all but five misguided counties in) Wisconsin?

Culver’s

It was kind of Wisconsin to share the ButterBurger with the rest of the country (or a good portion of it at least). While the rest of the country may love it, though, Wisconsin REALLY loves it.

Well, of course, and for reasons not necessarily tied to Butter Burger, or even their custard. Culver’s store owners, for instance, pay the salaries of their employees while their stores are being rebuilt after a fire. In an era of poor customer service, Culver’s stores seem to stand out in every community they’re in.

I’m sure you’ll be shocked — shocked! — to find that I’ve been to most of the other fast-food-ish restaurant chains on this map. I have not been to the West’s two most popular chains, In-n-Out and Whataburger. I am somewhat amazed to find Hardee’s as popular as it is given that so many where I have lived have closed.

This post deserves a song:
