Frost drives deep in the San Luis Valley, deep enough that everyone who works underground in Alamosa knows exactly how far down the cold reaches. Husmann Plumbing Inc spends its winters attentive to that cold, and snow removal belongs to the same watch: plowing drives and lots, clearing walkways, breaking up the ice that forms where a downspout drips and refreezes by morning. Storms arrive on a hard wind out of the west and leave the north side of every building loaded. The truck comes through in the dark so nobody has to shovel their way out into a deep freeze. Clear ground, clear entry, and the day starts on time.
