First frost in the hamlet of Belgium shows on the low ground near the Oneida River before it touches anywhere else — a white skin across the grass at sunrise, gone by nine. Ground Force Property Services LLC reads that morning as a signal: mowing season bending toward cleanup season, and the plow gear due for a hard look. Through the warm half of the year the company mows, trims and clears yards; through the long white half it plows driveways and opens walkways after each storm. Clay winters hand out plenty of work and no sympathy, and there is real pride in being the truck that already came. Two seasons, one property, carried straight through.
