At two in the morning the Santa Fe corridor west of Englewood is nothing but sodium light, falling snow and the sound of a blade on gravel. Jim's Excavating Co. Inc. takes on snow removal when the storms come — plowing yards and lots, stacking piles where they will not block a gate, opening drives and access lanes. Heavy equipment suits heavy snow, the wet spring kind that comes off the mountains and settles at four hundred pounds a scoop. The crew keeps going while the town sleeps so the trucks can roll at dawn. Come daylight there is a plowed lot with square corners, and that is the report.
