All great geographical surveys define new boundaries, discover uncharted lands, and ask unanswered questions.

Can I get a Double Western Bacon Cheeseburger at the eastern based Hardee’s?

Does a Made From Scratch™ Monster Biscuit® taste as good at a west coast Carl’s Jr?

The east and west coasts, the midwest, the Rocky Mountains? Where is this boundary?

We will not answer all these questions but below is the definitive divide between this unnecessarily double named fast-food chain.

We start in the Pacific Northwest as Carl’s Jr holds all of the left coast and Idaho. Coeur d’Alene and Missoula start the split as Montana’s allegiance falls with Hardee’s. Yellowstone National Park provides a beautiful no mans land before northern Wyoming represents the east with Hardee’s.

This greasy line meanders through southern Wyoming before the state is divided as Casper goes Hardee’s Cheyenne goes Carl’s Jr. Colorado leans west here while Nebraska and Kansas look east.

The Oklahoma panhandle has neither of these chains as the divide follows the Kansas border before hitting absolute mayhem at the junction with Missouri and Arkansas.

Things get pretty tight in the Ozarks where Hardee’s slips into the Sooner State and the closest Carl’s Jr is only 30 miles away as the crow flies. A crow could eat fries from both in the same day.

Texarkana could go either way and Shreveport looks to east Texas Carl’s Jr. We end in the south as Houston keeps the Lone Star State consistent and southern Louisiana keeps its refined southeastern culture.

That was enlightening I need a Thickburger® and shake.
