"House of Cards" Films in DC--where? where?

Police cars lined up along Pennsylvania Avenue near 15th St.

Did you catch the fake motorcade? I ran down Pennsylvania, Constitution, and Independence yesterday late morning and was hoping to see someone setting up something, with no luck. Supposedly, they filmed at various locations (see below or go to DC site), but did not require any road, lane, or sidewalk closures. Bummer--this would have helped. I snapped a picture of police cars lined up along Pennsylvania Avenue near 15th Street NW; is this normal?

Locations:
3rd St NW btw Independence and Pennsylvania Ave
7th St NW btw Independence and Pennsylvania Ave
9th St NW btw Independence and Pennsylvania Ave
15th St NW btw Pennsylvania and Constitution Ave
