Hat number two (in an occasional series) is actually from an ethnic group that reside in the borderlands of more than one country. One of the countries had the nickname “The Land of A Million Irrelevants” during the Vietnam War, and another is the home of some of Asia’s strongest beers.
Good luck, and before anyone else asks, no, you don’t win the hat if you come up with the right answer.
(But I will tell you where you can buy one…)
