I live here.  Dozens of people I knew went.  The crowds walking down from Columbia Heights (not hotel/tourist territory) were enormous.  For every moderately politically involved person under 35 (and many older than that), it was the social thing to do on that particular Saturday. 
  
 Please shut the fuck up about things you don't know about.  Thanks.

Yea, I live here too. A lot people (me included) airbnb'd their place and left town. Still I would never try to give estimates on the number of protesters based on anecdotal evidence ....
