2017 NYC Veterans Day Parade

New York City hosted its 98th annual Veterans Day Parade, the largest celebration of service in the nation, on Nov. 11. “America’s Parade” featured more than 20,000 participants, with marching bands, people on floats, veterans’ groups and military units.

At 11 a.m. — the 11th hour of the 11th day of the 11th month — a solemn hush fell over Manhattan’s Madison Square Park as veterans laid wreaths under the Eternal Light Flagstaff to honor the fallen.

This year’s parade marks the centennial of the United States’ entry into World War I (1917-2017). The U.S. Air Force is this year’s featured service. The parade is also a key part of Veterans Day USA, a national network of events working toward the 100th anniversary of Veterans Day in 2019. (Yahoo News)
