Sarah Palin's presidential campaign bus tour is being billed as a family vacation, and the most visible member of the Palin pack along for the ride is little 10-year-old Piper. As the former Alaska governor is mobbed by media all along the East Coast, Piper's head pops up among the microphones, usually looking curious, maybe a little amused, sometimes wearing a pair from her apparently large sunglasses collection. Piper is the perfect age for this unusual family roadtrip--old enough to be fascinated by other humans, not old enough to be too cool to have fun. Take a look at the photo lineup.
