Blood flowed in the 4600 block of N. Kenmore at 4:00 a.m. this morning (see full story here).
It quickly congealed, of course, but it flowed again hours latet at 9:05 a.m. when the Chicago Fire Department stopped by to spray down the reddened pavement.
This is the usual procedure when the streets or sidewalks are stained with blood -- unceremoniously hose it down.
It was off the street and into the gutter, but the process aerosolized it. The air on Kenmore, however briefly, was literally bloody.
