Centerville sits in the Petit Jean River valley with the mountain standing off to the north, and the light down here changes by the hour as the clouds come over the rim. Dunnams Lawn an land management LLC mows, trims and edges yards through the valley and brings rough ground back down to a maintained lawn when a place has gotten ahead of its owner. River-bottom soil grows grass in a hurry after a wet spring, so the mowing turn tightens in May and holds until the heat slows things down. Fall work is leaves, brush and one last even cut before the valley browns out for the winter. There is a plain pride in standing at the end of a drive and seeing every line straight and every edge sharp.
