Reply #154: If you look at the third photo down with Obama on stage in the lower right

[whistle]

...and the perspective looking back toward the Capital looking dome building I woould say that the domed building is at least 450 feet wide so the plaza in front between the two rowsa of trees flanking the crowd and coming forward to the stage must be 500 feet wide by 2,000 feet long and that would be 1,000,000 square feet packed solid with standing people. Then there has to be people under and on the othere sides of the tree rows plus more people in the foreground on Obama's left.

There must be at least 1 million people in that crowd
