I don't get it. I don't. I don't get the people who live in neighborhoods where they're not just obsessed, but forced to maintain their yards to a certain standard by their neighbors. (It gets a little funny when HOAs and municipalities butt heads during a drought, though.)
I live in a rural setting, where the notion of someone having an acre yard being a sign of success is pretty damn funny. Still, if you look at my yard, there's snakeholes, there's crabgrass, dandelions, and all sorts of weeds and wildflowers growing. When do I cut it? When it gets ugly.
If any of the nearby city limits ever catch up with my property, though, I'll have to keep it mowed. Why? The nearest towns all have maximum grass height limits, after which point they send in the highest bidder to cut it for you. This is not in an affluent area; this is, imho, to punish desperately poor people for being poor and daring to have grass. In the Midwest. Where it's everywhere that there isn't a field.
And of course, right now, I hear multiple mowers running; mostly retirees who have thrown themselves at having a perfect yard.
If I could replace the whole damn thing with prairie grass, I would.
