U.S. Sen. Barack Obama yesterday visited the gravesite of his maternal grandfather at the National Memorial Cemetery of the Pacific at Punchbowl.

He also spent Day 6 of his Hawai'i family vacation playing golf, visiting the Pali Lookout and taking 12 children for shave ice.

Obama, who arrived in Ho-nolulu Aug. 8 with his wife, Michelle, and their two daughters, is scheduled to leave Hawai'i tomorrow.

Following a morning round of golf at Luana Hills Country Club in Kailua, Obama and a group of about 20 people went to the cemetery, where his grandfather, Stanley Dunham, a World War II veteran, is buried. Obama credits the Dunhams with raising him as a youth in Honolulu.

"Let's go see your great-grandpa," Obama told his daughters, Malia, 10, and Sasha, 7, before they set out for the gravesite. Obama carried a flower lei and was joined by his brother-in-law, Conrad Ng to the grave site.

At Island Snow in Kailua, he ordered keiki-size shave ice for the 12 children. "It is right before dinner. I don't want to get in trouble," he said.
