March is the heavy month. An upslope storm parks itself against the Front Range and Fort Collins wakes under a foot of wet spring snow, with Horsetooth Rock lost somewhere in the gray. Zak George Landscaping works that morning, blades down on driveways and parking lots, shovels and blowers along the walkways, ice knocked off the steps and entries where meltwater will refreeze by evening. Wet snow does not forgive delay; it weighs, it sticks, and it has to be moved before the sun goes off it. What a customer sees is an apron of clear concrete and a clean line at the garage door, which is the entire idea.
