The field is very wide, it looks like he's a horizon, no edge and no edge. But there are no much changing fields, here on their collective farms outlined by a cliff or forest edge. Well, maybe the neglected tractor driver did not finish much in what year.
Work in agriculture is over, especially in the spring, when the main job is sowing. Tractors rush back and forth, work almost to dark, and when the weather and adjust the night, by the headlights, moon and stars. While some stars when all the dust around, already on the creaking teeth and the solid layer lies on the sweaty face. the truth will see it at home only the wife met at the door. Laugh at and stretch clean towels.
Imagine the heat of the sun and a bottle of water, which is left far behind and you do not know - whether to go back, or suffer and reach the edge of the field ... What is precious that a simple sip of water ?? Now all this to me is the heroism of the workforce, an uncompromising belief in the future, in the bright future we now have.
