I thought what Mr & Mrs Halsey had created looked rather nice and much better than signs asking people not to park on the grass.
In many of our country lanes, the few residents that live on them have planted thousands of bulbs (daffs, tulips, etc) to herald the retreat of winter which means those lanes, when viewed from the top, look lined with gold and colour; really beautiful. The groundsmen just don't cut the grass there until those bulbs have stopped flowering.
Why can't common sense be applied? I can fully understand people wanting the front of their properties to look nice - maybe more attention should be paid to those who don't care and maybe, just maybe, it wouldn't seem out of place.
