Some Berthoud storms are just weather, and one or two a winter are an event — snow all night, plows working the highway, the plains gone white to the horizon by the time the sky lightens over Waggener Farm Park. XXXTREME SERVICES LLC works those from the front end, plowing driveways and lots through the dark, coming back for the second and third rounds, shoveling walks and stoops clear and salting the ice underneath. The measure is simple enough: are the drives open, can people get where they are going. Big snow is mostly stamina and sequence — push early, push often, never let it set up. Morning comes, and the town goes about its business anyway.
