I over planned my day and didn't make it to Arlington until 5:30 on a day it closed at 7. Fortunately, I did make it in time to see the eternal flame burning at Kennedy's grave and to watch the last changing of the guard at the Tomb of the Unkown. Both are well worth visiting.
The sheer number of gravesites is sobering and I have seldom felt such gratitude and patriotism as I did walking the grounds at Arlington. I recommend it to any and all.
