NEW YORK (AP) — It was a Fourth of July marked by solemn and spectacular. The nation has marked its independence with the reopening of the Statue of Liberty for the first time since Superstorm Sandy, extravagant fireworks that included a 19-burst salute to Arizona's fallen firefighters, and a musical tribute in Washington to those affected by the Boston Marathon bombing. After the celebrated opening of Lady Liberty early Thursday, New York City's over-the-top fireworks show drew millions to watch four barges loaded with 40,000 shells light up the night sky over the Hudson River. In Arizona, a more subdued celebration paid tribute to the firefighters killed in last weekend's wildfire, with the names of the fallen read amid single firework blasts. Boston's concert and fireworks marked the city's first large scale gathering since the April bombings that that killed three and injured hundreds. And in Washington, thousands crowded the National Mall where Neil Diamond sang "Sweet Caroline" in tribute to victims and survivors of the marathon bombings.
