March snow on the Front Range comes heavy and wet, the kind that bends the honeylocusts along Huron Street and is mostly gone by Thursday. Alex and Sons LLC works the hours before that: plowing, shoveling walks, opening driveways and putting down ice melt where the gutter meets the curb and the water refreezes overnight. There is a particular satisfaction in a drive cleared at four in the morning — black pavement showing, a car backing out at seven as if nothing had happened at all. Storms out here can stack up two in a week or skip a month entirely, so the work is about being ready rather than being scheduled. Snow removal for Northglenn, Thornton and Westminster, for as many rounds as a storm asks for.
