My veggie gardens are doing just fine with an every 3rd day of watering (secret is to plant crops tight to each other for shade and water retention, I am such a farmer:) but my neighbours who have grass are watering in vein. The water evaporates faster then the grass can take it up and anyway, grass still burns in full sun, water or no. I'm eating tasty carrots, tomatoes, chards, kale, lettuces and broccoli, while my neighbours "crunch" across their grass! (I'm soooo mean:)
I call this the "Cow Days of Summer".
