This was Sunday's sunrise over the vineyards behind our house. The vineyards stretch out back for a mile or so before giving way to other kinds of agriculture and forests.
You can see that the vines have been recently trimmed. The growers use big tractors with a cutting blade attachment that straddles each row, neatly trimming the tops and sides. Sometimes I see people (growers or their employees) walking the rows, trimming some of the vines by hand. I suspect they're removing leaves that are covering or shading the grape bunches so the grapes stay dry and ventilated; that way they'll ripen properly and not rot on the vine.
