Sarah Palin On A Motorcycle At Bus Tour Launch (PHOTOS)

Sarah Palin jumped on the back of a motorcycle on Sunday in launching a bus tour that will take her across the eastern United States.

The former Alaska governor took part in the "Rolling Thunder" motorcycle ride, which starts at the Pentagon and finishes at the Vietnam Memorial in Washington, DC.

The AP reports that the potential presidential candidate's family was by her side:

Palin chatted with other motorcyclists and joked about how warm she is in her leather jacket. Temperatures in Washington are expected to climb near 90 degrees on Sunday.
