Irondequoit Creek runs its wooded valley along the western edge of Perinton, and the land there rises and falls enough to make every lawn its own problem to solve. Natale Landscape LLC takes those on across Fairport — mowing, trimming, edging and yard cleanups through the growing season, plowing and snow clearing through the other one. A slope cuts cleanly only when someone has thought about the direction of the pass, and it shows plainly when they have. Winter on that same ground means knowing where the snow can go before you start pushing it. It is one idea worked in two materials.
