Harvest night

Yesterday, well actually tonight at 1:30 there was an incredibly noisy hubbub right in front of my window.
Which seemed a bit weird, considering that all there is is a field. And some trees. And another field. Oh, and a little road. And another field.
Turns out that they were harvesting the crops in the middle of the night with threes farm machines. They had reaped the wheat during the day and left the straw to dry. In the night it was made into bales, stacked and partly taken away.
It looked like a choreography...
