Lake Erie builds its weather to the southwest and sends it up the Niagara, so a Grand Island winter tends to arrive sideways and in a hurry. Armstrong Landscaping and Snowplowing Inc. answers with plow trucks out ahead of the school buses, driveways opened down to bare pavement, walks salted while the sky is still the color of a nickel. By May the same island ground is soft and green, and the work turns to mowing, edging and the tidy beds that make a yard read well from the road. There is real satisfaction in both halves of that year — a clear drive at five in the morning, a clean cut at five in the evening. Snow and lawn service across Grand Island and the neighboring river towns.
