Based on that map, we absolutely, completely and totally filled their 240,000 area, and partially filled their 940,000 area, and that is not counting the 100 to 200 thousand who remained on Pennsylvania Avenue throughout the event.
My husband & I attended the event. We got to freedom plaza at 9:25 and it was pretty full then. We stood around for about 20 minutes and then the a large portion of the crowd in front of us started moving down Pennsylvania Ave, we were nowhere near the beginning of the crowd. We walked a block down Pennsylvania and then got over on the sidewalk to watch people going by around 10:20am (the march wasn’t even supposed to have started until 11am. We watched people for 1hr & 20min and the crowd coming down Pensylvania was still thick & showed no signs of thinning, so we joined the crowd again. We met a couple guys at an intersection that were doing an estimate of people - and said that at 11:30 there were over 400,000 that had passed them. They had been at that intersection since 9:30 & that there were already people ahead of them when they stopped to count. We finally got up near the the crown at the Capitol around 12:30 & there were still people coming up Pennysylvania. So at minimum I can verify a thick crowd of people were walking from the Freedom Plaza to the Capitol for 2.5 hrs.
