Sarah Palin and Piper Palin in a sea of bikers

Sarah Palin and her daughter Piper Palin are surrounded by motorcycle riders as they prepare for the annual Rolling Thunder rally for POW/MIA. The scene was in Arlington, Virginia on May 29, 2011. Rolling Thunder was an annual ride in and around the U.S. capital (and capitol) to honor and call attention to prisoners of war and the missing in action, especially those from the Vietnam War. Sarah Palin was the Republican candidate for vice president in 2008.
