February on Oakwood Boulevard is salt-white and low-skied, and the lots have to be open whether or not the storm agreed to quit overnight. J. Q. TAG plows commercial pavement and residential drives, clears the walkways, and salts the entries and aisles where the pack turns slick underfoot. A lot cleared before opening is a business that never lost a morning to the weather. Storms here tend to arrive in waves, so it is often two or three passes rather than one heroic one. Blacktop showing through by sunrise — that is the mark to hit.
