you see FACEBOOK is the root source for the college kids to be pestered. My assumption is just as you say about Arlington, VA.(i know Arlington,VA. well having been a resident of Maryland for a time ) these people will be going door to door in the heavy populated areas where there are lots & lots of apts, undocumented workers (which there are many in Arlington) and the big box store parking lots, can’t ya’ just see it? I’ll bet you a dime to dollar they won’t be going ‘round to Foxhall Road in D.C. though or even going White Flint Mall in Rockville, MD> too upscale.
We used to live on Foxhall Road and you are absolutely right about all those areas you mentioned!
