Some Grand Junction mornings the fog freezes onto everything overnight and Main Street wakes up furred in white, every sculpture and bare branch outlined in ice. Nash Maintenance gets out ahead of that — plowing lots and drives, clearing sidewalks, shoveling entryways, spreading ice melt where boots are going to land. Downtown doors open early, and nobody should have to negotiate a glazed step to reach them. The measure of a good night's work is a walkway that nobody notices at all.
