Up in Mentor Township the green season arrives late and leaves in a hurry, so every mowing week counts. Northern Cheboygan County is jack pine and hardwood and sandy two-tracks, and a lawn carved out of that forest edge is a small, deliberate clearing that has to be kept. Atlas Tree & Landscaping Inc. mows, trims and edges those clearings through the long north-country evenings, when the light hangs on past nine and the cool comes up off the low ground. Spring work here means pine needles and winter's litter hauled off before the grass wakes; October means leaves gathered ahead of the first hard freeze. What is left is a yard that reads as tended right up to the line where the woods take back over.
