Sarah Palin rides on the back of a motorcycle

Former Republican vice presidential candidate Sarah Palin rides on the back of a motorcycle at the 2011 Rolling Thunder rally for POW/MIA (prisoners of war / missing in action). This photo was taken in Arlington, Virginia on May 29, 2011. Sarah Palin was born in 1964, so she turned 47 the year this photo was taken. The original caption also mentioned Sarah's daughter Bristol Palin, as if maybe she was driving the motorcycle, but that's not Bristol Palin in front of Sarah. There may be a passing resemblance, but Bristol turned 21 that year, and this woman looks older. Also, other photos from the event show Bristol in a dark shirt and without braids.
