Ishiah McKissick, 15, right, and Troy McClemore, 18, take a break while working out at TKO Boxing, a local boxing gym near where Muhammad Ali used to train Monday, June 6, 2016, in Louisville, Ky. "I liked how flashy he was," said McKissick of Ali. "And he did lot of good for this city." In a city accustomed to capturing the world's attention for just two minutes during the Kentucky Derby each year, Ali's memorial service Friday looms as one of the most historic events in Louisville's history. Former presidents, heads of nations from around the globe, movie stars and sports greats will descend upon the city to pay final respects to The Louisville Lip. (AP Photo/David Goldman), APTOPIX
