The Natchez Trace Parkway is a scenic byway that rolls 440 miles through Mississippi, Alabama and Tennessee. A unit of the National Park Service, the trace winds its way through lush landscapes, diverse ecosystems and interesting historical sites. Originally the trace was a foot path for Native Americans and later used by early pioneers and traders. Today it's popular for motorists, cyclists and others seeking adventure, tranquility and a peek into America's past. Most recently, it was the chosen location for a remarkable initiative by four women interested in promoting living kidney donations. All living kidney donors themselves, these women tackled the parkway's entire 444 miles, beginning in Nashville, Tennessee, and finishing in Natchez, Mississippi….and did it in only four days. This week the Traveler's Lynn Riddick visits with these donor athletes to learn about their journey that they call "4Women 4Kidneys 444Miles 4Days" and also to get a sense of what the Natchez Trace Parkway can offer to everyone.
