As someone who lives in the San Bernardino foothills I can assure you grass doesn't just grow it dries out and gets replaced by an invasive species of central Asian plant. The housing tracts must be baptized in hundreds of invasive tumbleweeds followed by an inferno caused by a Bic lighter.

Grew up in the countryside where our yard ended where my dad stopped cutting the grass, one time I messed up his line and we found a horseshoe pit while fixing it, so we got a bigger yard with horseshoes 😂
