From a White House pool report filed Thursday by the Wall Street Journal's Colleen Nelson, who was covering the Obama family's ongoing vacation in Hawaii:

President Obama's motorcade made its way to Honolulu, passing by stunning vistas while occasionally being slowed by congested roads. After a 30-minute drive, Obama and daughters Sasha and Malia arrived at the National Memorial Cemetery of the Pacific at Puowaina Punchbowl Crater.

Obama's grandfather, Stanley Dunham, is interred at the cemetery. ...

Four minutes after arriving, Obama and his daughters were back in the motorcade.
