Post-inaugural Wasteland

Here is a revised estimate of the crowd size at the Inaugural ceremonies. Once predicted to be 4 million, the actual crowd seems to have been a good deal smaller, based upon estimates from the satellite views. WaPo gives various estimates in its article.

An account of the huge trash cleanup indicates that the crowd gathered to celebrate on Jan 20th did not leave a light carbon or garbage footprint. And below is a video that says it all, except for the port-o-let issue.
Calculations from our school's 8th grade algebra students reveal that NO WAY was 5000 port-o-lets enough to hold all the crap! We're planning to suggest this intellectual exercise as an addition to the next edition algebra texts. Similar calculations of volume and capacity, suggested by the articles and video, are welcome.
