Music:angry foxes in a large metal barrel. Or, muckspreading, possibly
It is 20 minutes to 1am in the morning, and someone is employing a tractor, lights and a bizarre swooshing thing on the field opposite my house. I think it may be muckspreading. As the valley is otherwise completely silent at this hour, the noise, which would normally be unnoticeable, is quite striking. It sounds like he is energetically circulating a number of angry foxes in a large metal barrel.
WHY would anyone be muckspreading at 12:40am? WHY?
At least he's unlikely to be very long about it. It's not a big field. Which just increases the mystery of the 'WHY AT 12:40am?' question by an order of magnitude.
