February in Lyons has a habit of relenting for a single day — melt running down the gutters of the long village blocks, then freezing solid again by nightfall. Robert O's Landscaping and Snow Removal LLC plans for that swing, plowing and shoveling through the storms and salting the walks that turn glass-smooth when the temperature drops back. Once the ground lets go in spring, the same trucks come back with mowers for the cutting, trimming and yard cleanup that carry through to fall. Two trades, one route, block after block of the same familiar addresses. Knowing a street well is most of what makes the work quick.
