Rush hour generally hits its peak at about 7 a.m. Pedestrians hustle along the sidewalks or peddle along on the city's bike lanes, usually narrow strips of sidewalk painted green that started to appear about a year ago, while workers and students who can't walk or bike to where they need to go load onto the subways and fill the city's buses and electric streetcars. By about 6:30, long lines of men in neckties or olive-colored work clothes and university students in their uniforms — white shirts or blouses, and dark trousers or skirts accentuated by red ties or scarves — can be seen waiting for their cross-town rides, which are usually standing-room-only. With North Korea now on one of its "loyalty drives" stints, when the citizens are called on to show special devotion to leader Kim Jong Un and often put in extra hours to boost productivity, Women's League units are out in force in front of subway entrances and other strategic locations to dance and wave red flags as loud patriotic music blares from boom boxes.
