Watering the vines

I think the new grape vines out back are too young and fragile for this heat wave we're having, so the growers are working to ensure they survive by giving them water. At least, that's the story I've conjured in my mind about what's going on here (maybe they'd water them anyway?). Four people, each armed with a hose that's connected to that big machine, walked behind it as it crept along, keeping the ends of the hoses aligned with the rows they were watering so there would be no waste. With that big machine, they could do four rows at the same time.

I was very far away when I took this photo. You may be able to see the people just to the left of the tractor.

Meanwhile, the heat wave continues. Today looks like it might be the hottest day before it cools down again. We shall see.
