So, I was in Wisconsin and saw this $5 22-oz Old Fashioned on the menu. Five Dollars? 22 ounces?

That day, I learned that a Old Fashioned in Wisconsin consists of a classic Old Fashioned that they add a bunch of Sprite into. (or grapefruit juice if ordered "sour" instead of "sweet")

I don't know if this is a well known thing to r/cocktails.
