We’ve been hearing ad nauseum about border walls, but who knew there were butter walls? Even some folks in Wisconsin are just now realizing that their state—“America’s Dairyland”—has an impenetrable fat fence. No immigrant butters from France, Italy or Ireland, or any other foreign country, are permitted on Wisconsin grocery-store shelves. At least one Kerrygold fan has resorted to driving to a neighboring state to score some Irish butter. I’m a Kerrygold enthusiast, too, but my laid-back state (California) lets me have all I want, no questions asked.
