Zach Boatright, Celina, goes through a container of marbles in his grandfather's garage sale booth set up in the parking lot at Chief's plaza in Celina on Wednesday. He is one of many local residents selling goods in the 24th annual World's Longest Yardsale, which kicked off today and runs through Sunday. The 675-mile route begins in Michigan and follows U.S. 127 through Ohio, Kentucky and Tennessee before switching to Lookout Mountain Parkway and continuing to Gadsden, Ala.
