Say It Ain't So, Lance

Lance Armstrong is facing doping allegations again. Although federal investigators in February closed a two-year investigation without bringing criminal charges, the U.S. Anti-Doping Agency has filed new doping charges. Armstrong insists that he's innocent and that he has passed more than 500 drug tests. Of course we've heard doping denials before from many athletes that turned out to be false, but I really hope that in this case Lance really is clean. We'll see.
