Every August, the World’s Longest Yard Sale snakes its way 690 miles from Gadsden, Alabama to Hudson, Michigan. With such an embarrassment of riches, the shopper may not know where to start. (The stopping part is easy: you run out of money and/or room in the car). Here’s a suggestion: the southernmost part of the route follows the scenic Lookout Mountain Parkway 93 miles from Gadsden through a corner of Georgia to Chattanooga, Tennessee. Since the Alabama portion of the route alone boasts some 1000 vendors, you will probably be throughly over the whole experience by the time you hit Chattanooga. If not, no problem. Just keep following the U.S. Highway 127 Corridor from Chattanooga for another 600 miles.
