DC traffic: Native Nations Rise protest march led by Standing Rock Sioux Tribe, 10 am-noon Friday. wapo.st/2mFx3g5

#SafeTrack: L'Enfant Plaza is crowded but I wouldn't avoid the #wmata transfer here from Yellow to Silver/Orange. It's not that crowded.

#SafeTrack: Some of these folks exiting Yellow #wmata trains at L'Enfant will need to skip first Silver/Orange because of crowding.

#SafeTrack: Very big transfer from Yellow Rush + to Silver/Orange at L'Enfant Plaza. #wmata

#SafeTrack announcements on platform & aboard this #wmata train are good, clear.

#SafeTrack: so far, it's a low-key surge at Springfield. Very few stop to check sign advising there's no #wmata Blue Line.

#SafeTrack so far: I've seen no crowding on #wmata platforms or trains between L'Enfant-Springfield. Many 8-car Yellow Rush +.

Haven't seen L'Enfant Plaza so crowded since Obama's first inaugural. Very slow exit from both levels. #WomensMarch

Crowd that walked on East Capitol from RFK buses streams onto Capitol grounds for #womensmarch.

People from RFK buses reach Lincoln Park on way to #WomensMarch.
