Harlem Avenue never really sleeps — it only gets quiet enough around four in the morning that you can hear a plow working two blocks off. SME Landscape Chicago LLC takes that hour, moving snow off the lots, walks and approaches around Oak Park before the doors unlock and the first cars swing in. The city glow sits low on the eastern sky the entire time, miles of streetlight bouncing back off the clouds. Snow work at this scale is a race against a clock nobody agreed to: it has to be done, and done before. Turning a white lot into a black one by opening time is a good way to start a winter day.
