NASCAR's getting younger

Twenty-year-old Kyle Busch's win in Sunday's Sony HD 500 (surely the first race named after a data format) makes him the youngest driver ever to win a Cup race, and highlights the ever-decreasing age of NASCAR's "young guns." The top 5 at Fontana included third place Brian Vickers, 21, and fifth place Carl Edwards, 26. Edwards also won Saturday's Busch series race, beating 19-year-old phenom Reed Sorenson, currently 4th in the championship standings.
Does NASCAR care? Oh, yeah. Kyle's "First Win" t-shirt went on sale the next morning at the NASCAR superstore.
