Blue sky is reflected in a muddy tractor rut.
We have no idea what's happening back there. At one point I thought he was improving the path/road that went from the vineyard down into the ravine; there's a paved road that runs through the ravine along which are many houses, maybe even his, so that's a possibility. We don't think a house is being built up by the vineyard because there are no utilities up there. So we're left wondering what's going on.
