WASHINGTON — Hundreds of thousands of holiday wreaths will be laid at Arlington Cemetery by volunteers this weekend as part of the annual Wreaths for America celebration that honors those who have served. 

While the wreaths will be up all weekend, a larger scale wreath-laying happens Saturday at 8:30 a.m. The wreaths will be up for four weeks, with the last day of showing on Jan. 11. 

For the volunteers of the veteran organization, the day of remembrance is meant to symbolize a lifelong service.

"We understand we have Veterans Day in the fall and Memorial Day in the spring, but our service members sacrifice their time and safety every single day of the year to preserve our freedoms," Wreaths for America's mission statement reads.

"In many homes, there is an empty seat for one who is serving or one who made the ultimate sacrifice for our country," the statement continues. "There is no better time to express our appreciation than during the hustle and bustle of the holiday season."
