we live on 1 acre. my wife was nice enough to agree to NO lawn. it's all trees, ground covers and nature. even along the curb she planted annuals and put down lots of mulch.
our next door neighbor followed suit. he used to cut his lawn then seveal years ago decided to let it go natural. he only worries about the first 15 feet from the edge of the road (no sidewalks).
no complaints from the neighbors and no herbicides nor lawnmowers
