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 this past week has brought protests and violence to Senegal after demonstrations over a presidential election this coming weekend led to clashes with riot police. We've got NPR's Ofeibea Quist-Arcton on the line from the capital Dakar to tell us what is going on there.

Good morning, Ofeibea.

Former Pennsylvania Senator Rick Santorum has been the hot story in the GOP presidential contest this month. Over the weekend, Santorum raised eyebrows with comments on public education, prenatal testing and what he called President Obama's "phony theology." Santorum was making waves just days ahead of the next Republican debate on Wednesday, and the next primaries in Michigan and Arizona six days later.
