Check-in – The Travel Guide

A look at an annual shopping spree along U.S. Highway 127 that spans four days, four states---Kentucky, Tennessee, Georgia and Alabama---and 450 miles. The sale was first held in 1987 and attracts patrons who hunt for items such as handwoven quilts, baseball cards, church pews and bird baths. The hour features self-proclaimed "garage salers" (who fill their cars with treasures gained during the event), discounted fixer-uppers, one-of-a-kind crafts, and unique antiques and trinkets. Host: Chris Wragge.
