No. I'm just a professional observer of big demonstrations. The March for Life is always a classy looking crowd. Crowds attending Republican inaugurals are presentable and well-behaved. The Promise Keepers were a good looking crowd, as the Glen Beck and Tea Party crowds, etc. As a general rule, however, the further left a group is, the more slovenly the attendees. Yesterday ran counter to the trend.
I've not seen any reports of the cleanliness/litter situation after the Trump inaugural. The trash differential has become a very telling indicator of the character of events. I wonder if tradition held on Friday, and the Mall was left as clean as it was prior to the event.
