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.
Now that’s really interesting. If I plugin 150 minutes instead of the 90 minutes suggested by the video, the total that marched goes up to 387K. Very encouraging.
That makes the total estimate jump to 718K.
