On a still Sunday street in Dahlonega you can hear the difference a mowed yard makes — a block that both sounds and looks looked-after. Humble Servant Lawn & Handyman Services works those residential streets and the hill roads above them: mowing, string trimming, edging, blowing off drives and porches, and cleanups when the year turns over. Plenty of the yards belong to people who used to do it all themselves and would rather it still be done the same way. That sets the standard — attention to the corners nobody photographs, the fence line, the mailbox post, the strip of grass along the curb. Ordinary yards, kept well, one after another down the street.
