Sarah Palin Joins Bikers for 'Ride to Freedom'

Sarah Palin is joining a group of about 400,000 motorcyclists for the annual Rolling Thunder "Ride for Freedom," which coincides with a bus tour that is renewing speculation about her 2012 presidential ambitions. Palin, who has no official speaking role at the event, is kicking off her bus tour in Washington, where she will participate in the annual event, in which bikers ride from the Pentagon to the Vietnam War Memorial to draw attention to missing service members and prisoners of war.
