Alex Williamson, 8, doesn't look very hungry — in fact, he's a little chubby. But Alex, who lives in Carlisle, Pa., is one of 17 million children who live in U.S. households where getting enough food is a challenge.

The Obama administration has pledged to end childhood hunger in America by 2015. A key element of that challenge is to make sure the food hungry children eat is nutritious. They're lofty goals that will be difficult to achieve.

Every Child Matters in NH will once again be putting Concordians underwater with a dunk tank at Concord Market Days, Thursday, Friday and Saturday (7/15-7/17).

Scheduled dunkees include Mayor Jim Bouley (Thursday at noon), Concord Police Detective Sean Ford and Officer Joe Wright (Thursday 4:30 to 5:30 p.m.) and City Councilors Amanda Grady (Thursday at 2:00) and Steve Shurtleff (Friday at noon). There will be more local celebrities added, so be sure to warm up your throwing arm. All proceeds will benefit after school programs in NH.
