This President's Day, a group of historians in Washington, D.C., decided they wanted to do something different to recognize the legacy of Abraham Lincoln. But how do you memorialize someone who is already one of the most memorialized people in history?

Their solution: to physically illustrate Lincoln's importance by creating a tower of books written about him. The tower measures about eight feet around and 34 feet — that's three and a half stories tall.

Through his many New Yorker covers, Barry Blitt has become one of the pre-eminent satirical cartoonists of America's recent presidents. He is probably best known for his controversial 2008 cover of Michelle and Barack Obama, dressed as a Muslim and a militant with an AK-47, fist-bumping in the Oval Office.

This year would not be a good year for ice cream. In fact, there would be none at all if we relied on the technique George Washington used at Mount Vernon, his Virginia estate that's perched on the banks of the Potomac River.

His source of ice was the frozen river. Given the warm winter we've had here in D.C. , there's no chance. Seems the weather is nothing like it was on Jan. 26, 1786, when Washington wrote in his journal:

"Renewed my Ice operation to day, employing as many hands as I conveniently could in getting it from the Maryland shore, carting and pounding it."

South Korea conducted live-fire military drills near its disputed sea boundary with North Korea Monday, despite Pyongyang's threat to respond with a "merciless" attack.

North Korea did not carry out the threat as it focuses on internal stability two months after the death of longtime leader Kim Jong Il and prepares for nuclear disarmament talks with the United States later this week. But with American forces scheduled to conduct additional military exercises with ally South Korea over the next few months, tensions are expected to remain high in the region.
