If you look closer at the picture, you’ll see a stage in front of the West Lawn grassy area. 912ers were positioned in front of that.
This photo is from Promise Keepers march years ago.
This is not the 9/12 photo, because (a) it’s a sunny day and (b) there’s nobody on the Capitol Bldg lawn.
We were actually first directed to the Capitol Bldg lawn and told we could not be on the Mall because there was some other event (a “hip hop family rally”) scheduled for the mall. However, the other event was not very heavily attended and I think there actually finally was spill over onto the Mall, because the authorities were very restrictive about letting people onto the West Lawn (right in front of the Capitol Bldg on either side of the steps and the “pit” in front of them), and there was no place for the huge crowd to go because Pennsylvania Avenue was completely blocked.
