This trip through the Bluegrass State showcases two Kentuckian pastimes that rely on speed — fast cars and majestic horses — one that requires careful aging and one that came about very, very slowly. In Bowling Green, you can hop in America’s Sports Car and take a lap as quickly as you can. Just up the road in Cave City, you can take a lap through the longest cave system in the world, a geological formation that took 10 million years to form. And between Louisville and Lexington, you can sip some of the finest whiskeys in the world.
