Sarah Palin Bus Tour Takes Former Governor Across Eastern United States

Sarah Palin is on the road, stirring speculation with a bus tour that she may be laying the groundwork for a presidential campaign in 2012.

The former Alaska governor's trip kicked off Memorial Day weekend in Washington, D.C. At the launch, she jumped on the back of a Harley and participated in the "Rolling Thunder" ride, which began at the Pentagon and concluded at the Vietnam Memorial.

The "Rolling Thunder" website describes the group as an organization dedicated "to bring awareness to the plight of prisoners of war (POW) and to those missing in action (MIA)."

Palin initially remained mum on where her travels would take her. Her itinerary reportedly includes stops in Pennsylvania, Massachusetts and New Hampshire.
