Along the I-90 corridor the big lots have to be open before first shift, and a storm that begins at midnight does not care how many acres are involved. Tecza Landscape Group works at that scale, plowing lanes and aisles, opening entrances, keeping walks and doorways passable while the snow is still coming down. Winter here rarely arrives on a convenient schedule, so routes get run more than once and the entries get treated where traffic packs it hardest. An empty parking lot at dawn, striped clean and dark, is worth being proud of. By seven it is full and nobody remembers the night at all.
