Obama at Stonehenge: 'How cool is this?'

President Obama did a little historical sightseeing Friday before returning to the United States after the NATO summit in Wales.

He took a guided tour of Stonehenge, the prehistoric monument in Wiltshire, England.

"How cool is this?" Obama told reporters. "Knocked it off the bucket list."

While walking through Stonehenge, Obama also said: "It's spectacular, it's spectacular. It's a special place."
