Walk the loop at McIntosh Lake in June and the cottonwoods are a wall of green; walk it in January and you can see clean through them to the mountains. Green Man Lawn and Landscape works both versions of Longmont, mowing, edging, trimming and cleaning up beds while things are growing, then plowing driveways, clearing walks and treating ice once the trees go bare. Hedges and borders get shaped so a property has a line to it, and in winter that same line is what a plow follows. There is a quiet pleasure in knowing a yard well enough to work it blind under six inches of snow. Whatever the month, the place looks like somebody is paying attention.
