It looks as though...

...somebody's working today as there's an out of shot works van to the right of the roller machine. They don't usually do that on a Sunday!

This is the site of AG (aerogenerador) 20 with

- the cable trench to the left
- the very visible waste recycling bin that they don't always notice
- the rolling machine whose beeping woke me up yesterday morning and
- the sign telling you that you can't pass if you don't work there and warning you of the changing levels... in other words, there's a dirty great hole in the ground!
