In Mammoth Cave National Park, where the Green River winds through karst valleys above the world's longest cave system, a ferry still crosses the water the old-fashioned way. No bridge, no tunnel - just a flat deck, a cable strung across the river, and a diesel engine that pulls the whole thing from bank to bank. The Green River Ferry has operated since 1910, connecting roads that would otherwise dead-end at the water. It's free, it's essential (the nearest bridge is miles away), and it's a working artifact of how Americans crossed rivers before the highway system decided rivers were obstacles rather than boundaries. You drive on, wait three minutes, and drive off on the other side, having briefly experienced transportation from a century ago.
