Does Dairy Queen close for winter?

Dairy Queen stores are usually franchises, so hours of operation are up to the franchise owner. In locations where it actually gets cold in the winter, the owner may see little point in keeping an ice cream store open.

Some Dairy Queens are "Braziers", which means they have a grill and serve Hamburgers as well as ice cream and frozen novelties. These are more likely to stay open.

At least a few DQ franchises are "walk-ups" with no inside seating. These are less likely to stay open.

A couple of concrete examples:

The DQ stores in St. Joseph, MO are (at least when I was living there) walk-ups without braziers and did not remain open in the winter.

The DQ store in Cameron, MO (40 miles away, so roughly the same weather) had a brazier and a drive-thru window and DID remain open in the winter.
