Downtown storefronts on Chicago Street have to be walkable by the time the doors unlock, no matter what fell overnight. V.I.P. Services Group takes that early window: sidewalks shoveled to the curb, entryways opened wide enough for a stroller, parking areas plowed and the ice treated where the shade never leaves. Snow along a business front has nowhere to go, so it gets moved rather than merely pushed aside. There is a quiet hour before opening when the walks are bare and the de-icer has just started working, and that hour is the entire job.
