Ah, the hip flask. Perfect for outings in which you bring your own whiskey. Years ago, my wife (then-girlfriend) Carly gifted me an engraved flask. It was a very thoughtful gift I’ve used a handful of times. Some folks I know swear by their hip flasks. Whether it is sneaking a bit of whiskey into a football stadium, concert or parade, hip flasks do serve their purpose. Especially nowadays, when whiskey’s popularity is booming.
