Blue hour on a January afternoon in Oswego lasts about twenty minutes, and it makes new snow on a paver walk look like something poured rather than fallen. M & M Outdoor Design and Hardscaping clears those surfaces with a careful hand — shovels and salt where a blade would gouge, plowing where there is open pavement to work with. Steps, landings, front walks and the path out to the side gate get opened by hand, because that is where people actually put their feet. Drives are pushed back to the property line so the piles don't creep inward over a long winter. The snow leaves in March; the stonework has to still be there.
