We started by exploring the Welcome Center and an exhibit on World War I. Next, we took a tram to the Tomb of the Unknown Soldier. We solemnly watched the guard and explored nearby memorials, such as one for the Space Shuttle Challenger, as well as visiting the grave of a Medal of Honor recipient, 2d Lt. Audie Murphy. We went back to the Tomb of the Unknown to observe the changing of the guard ceremony. Lastly, we visited the Arlington House (Custis-Lee Mansion) and explored the house and gardens before heading back to school. Throughout our trip, the students showed great respect at Arlington National Cemetery and DEA Museum and I was very proud of the mature way they conducted themselves.
