March is when Denver snow stops being polite. It comes in wet and heavy off the plains, bends the cottonwoods along the river bottoms, and packs into the lots around Globeville and Elyria-Swansea like something poured rather than fallen. A&J Landscaping & Snow Removal service reads that difference in the first shovelful and plows accordingly — pushing early, pushing often, so the drifts never get a chance to set up hard against a gate or a loading door. Walks get cleared down to the surface and treated at the shady north edges, where the melt refreezes long after the sun has done its work everywhere else. There is a particular satisfaction in a drive that's open before the first shift arrives and nobody has to think twice about the weather.
