At Arlington Cemetery we walked around a bit and then visited the Tomb of the Unknown Soldiers. We didn’t get there at a time to see the changing of the guard, but we did get there to see some presentations of floral wreaths by schoolchildren. There were three different wreath presentations, each with 4 schoolchildren and a lot of ceremony by the soldiers involved.
Here’s a video we took of the wreath ceremony: (click here)
