Come February the parking lots off 18 Mile have grown mountains — plowed snow stacked into the corners until it swallows the good spaces and refuses to melt. Rollerz Snow Removal & Hauling takes the mountains away. Plowing and lot clearing, walkways and entrances shoveled, ice treated, and the piles loaded out and hauled off once there is nowhere left to push them. It is loud, cold, floodlit work that happens while the city sleeps, and it is the reason a lot looks ordinary again at eight in the morning. A big flat property in Sterling Heights holds an enormous amount of winter, and somebody has to carry it out.
