“Bluegrass, Bourbon and Beers” Kentucky. Kentucky’s home to the world’s longest cave system (Mammoth Cave National Park), but there are plenty of things to do above ground in the Bluegrass State. Take, for example, the endless beer fests, events and more that Kentucky’s craft beer community hosts. Bourbon isn’t the only drink that flows through Kentucky.
