Oh man, that had to have been a moving sight. I'm glad you got to see that.It truly is. We had a layover in DC a few years back and drove from the airport at like 5am, wide awake decided to stop at Arlington whilst it was quiet. It was kind of misty with the grass all covered in dew, an incredible atmosphere to the place.
Was just after Remembrance Day so there was a wreath laid on each cross too.
