Three in the morning on Ryan Road, and the only things moving are a plow, a salt spreader, and the snow itself coming sideways under the streetlights. That is the shift HANNA'S SNOW REMOVAL & GROUND MAINTENANCE keeps. Clipper systems drop out of the northwest onto Macomb County with very little warning, and the difference between an easy morning and a rough one is who was awake at two. Driveways opened, walks and steps cleared, ice treated before the refreeze locks it down — the list is short and the timing is everything. There is a particular satisfaction in pulling away at first light from a drive that is black and clear while the rest of the block is still white.
