Fog lies low in the fields around Chickamauga before the sun clears the ridge, and that is the hour the mowers start. Avakian Lawn Maintenance keeps yards across this Walker County town — mowing, string trimming, edging along walks and drives, and blowing the clippings clear so what's left behind is stripes and a clean line. This valley rewards straight work, and a lawn cut true settles into it like it belongs. By the time the dew burns off, the grass stands even from the porch steps out to the mailbox. Come evening the light turns gold over the ridge and the yard still holds its shape.
