Snow that begins on a Sunday afternoon in Fort Collins catches a town that had other plans. Duke's Landscape Company answers it anyway, plowing driveways and lots, opening the cul-de-sacs off Horsetooth Road where drifts curl in against the garage doors, clearing walks and treating the slick spots. Front Range storms often quit by dark and hand the night over to a hard freeze, so whatever gets cleared before sundown stays clear. There is a particular pleasure in the last pass of a driveway — backing out onto a street that is still white while the concrete behind you is not. Monday morning arrives and nobody is stuck.
