Winning came naturally to Al Unser Jr. Born into a racing family, he had a gift for finding the fast line on the track. By the time he was nine years old, he could draw the quickest way through the corner on paper and intuitively apply his sketch while on the go kart track. By his teen years, the innate sense for the fast way made him unstoppably quick when he was racing through the woods on a snowmobile. As his career progressed from the kart track victories to following in the footsteps of his famed uncle, Bobby, and father, Al, the wins grew in stature from junior titles to the very top echelon of his sport. Two Indy 500 victories. An IndyCar championship. Sportsman of the Year. In addition, Unser was not just a winning driver - he also possessed a boisterous and lovable personality. The fans and the press adored him. Al Unser Jr. was on the top of world. A CHECKERED PAST tells that story - but it doesn't stop there.
