Saturday, September 12, join communities across the country as we honor the nearly 3,000 lives lost on September 11, 2001, and pay tribute to the first responders and service members who answered the call in the days that followed. In partnership with the National Cemetery Administration, the National Day of Service and Remembrance brings volunteers together at more than 140 participating national, grant-funded, and local cemeteries across the country. Volunteers will help clean headstones and beautify these sacred grounds in tribute to our military members, veterans, first responders, and their families. Registration is free, but required.
