CALVERTON - Bugles sang and flags waved as hundreds gathered at Calverton National Cemetery today to honor the nation's fallen soldiers.

The cemetery is the resting place of more than 230,000 veterans, including Sgt. William McKenna, who died of cancer in 2010 after being exposed to chemicals from burn pits in Iraq.

McKenna's widow Dina delivered an essay she wrote about Calverton, saying she and her two children go there to play, share memories and enjoy their father's favorite treats.

"We can come here now and have a picnic with jelly beans and Swedish fish on his gravestone and watch it melt and make a fun mess of things, and it's not a scary horrible place anymore, even though that was the worst day of our lives," she said.
