Here is a link to a video put together by the Atlanta Area Council regarding the flag placement at the Marietta National Cemetery preparations for Memorial Day.

Over 18,000 Graves were honored by 1,596 scouts, girls and boys, as well as 623 adult scouters for a total of 2,219 on hand. The actual flag placement is over in about 45-50 minutes.
