Technically the world’s largest yard sale, the flea market known as the 127 Corridor is certainly the LONGEST outdoor market. Beginning on a highway in Jamestown, Tennessee, this flea stretches hundreds of miles through North Covington, Kentucky, and continues all the way to Gadsden, Alabama. There are more than 2,000 vendors along this tour who clear their schedules for three weeks every August. One can imagine the caravan of Winnabagos that make this annual pilgrimage. Countless treasures and and billions of collectibles hide among bric-a-brac and junk, but the people-watching and Southern hospitality alone are worth the trip.
