It's full of weeds. Kids can run around on weeds. It only requires a handful of mowings every year, then it goes dormant unless there are unusual amounts of rain (like this year). By late July, the grass has stopped growing, and it's only weeds, which I can control with a manual "weed whip." For better or worse, the weeds are drought resistant.

So I doubt the contention that my lawn requires water, fertilizer, or even weekly mowing. As the kids have gotten older, the need for an extensive backyard has diminished, and I'm gradually turning more of it over to the vegetable garden every year.
