The 9/11 Memorial and Museum in New York City, the Pentagon Memorial in Arlington and the Flight 93 National Memorial in Shanksville are offering special events commemorating the 25th anniversary. The ceremony at the 9/11 Plaza in New York City during which each victim’s name is read aloud is particularly moving. If you can’t be there in person, many events will be televised or streamed. The second part of the day – service – can be achieved by volunteering for a cause that matters to you, whether at your church, a charitable organization or a park.
