There is a very minor side street in town that has virtually no lawn but is home to one of the notoriously few “wealthy” individuals in town. He’s literally a workaholic, has no family, and still uses a flip phone because he’s both old and old-fashioned.
His house is a green event point.
Yet there are LOTS of lots (heh heh, puns) overrunning with wide open, public grassy space, playgrounds, parks, etc ALL over downtown that have literally zero green event spawn points.
They’d rather let an angry miser who’d just as soon take a .22 to someone “loitering” on the sidewalk for longer than 15 seconds outside his home, that is in a somewhat busy urban neighbourhood where only the upper middle-class or higher can afford to live, have one than countless areas scattered throughout an entire town.
