Highland Park keeps its ravines wooded and its evenings long, and on a July night the music carrying out of Ravinia mixes with the sound of a mower finishing its last pass. Abonce Lawn Maintenance & Snow Plwng tends lawns across this bluff town — mowing, trimming, edging and the seasonal cleanups that keep a yard looking cared for from the curb. The ground here rolls and drops toward the lake, so no two properties cut the same way, and that suits the work fine. What we're after is a lawn that reads as tended: even height, straight passes, clippings gone before we pull out. It's a good feeling to leave a street a little tidier than we found it.
