Downtown at five in the morning after a storm, the city is a page nobody has written on yet — Union Station glowing at the end of Wynkoop, the tracks under a smooth white sheet, the sidewalks unbroken from corner to corner. CAM Services - A Tendit Group Company works that hour, opening plaza walks, doorways and lots before the first trains run and the first badge swipes at the office doors. Snow in the core is a logistics problem as much as a weather one: nowhere obvious to put it, hard surfaces everywhere, and thousands of feet arriving whether or not the ice is handled. So it gets moved, stacked out of the way, and treated where the shade between towers keeps things frozen past noon. The measure of a good night is that by eight o'clock nobody notices anything at all.
