Sarah Palin chats with a biker

Sarah Palin (in motorcycle helmet at right) chats with another motorcycle rider as they prepare for the annual Rolling Thunder rally for POW/MIA (prisoners of war / missing in action) through Washington, D.C. This photo was taken in Arlington, Virginia on May 29, 2011. (We believe that is Sarah's daughter Bristol Palin between them at the back.) Sarah Palin was born in 1964, so she turned 47 the year this photo was taken; Bristol Palin was born in 1990, so she turned 21 that year.
