Summer in Buena Vista Charter Township comes in under big silver maples and stays late; the light hangs on past nine and thunderheads build up the valley all afternoon. Switzer Lawn Service works between those storms, mowing, trimming and edging yards along the township's long residential blocks while the ground is still dry enough to hold a wheel. Flat land shows every wobble in a mowing pass, which is exactly why the lines here run straight from curb to fence. Clippings come off the sidewalk, the border along the drive is cut in sharp, and the yard is handed back looking like someone paid attention to it. In autumn those maples let go all at once, and the leaves are cleared the same way, thoroughly and before the rain turns them to paste.
