I wrote a week ago about some building works on our street.
For the past two days there has been an enormous crane on the site. I always find cranes exciting  although I am not clear what they are for. In this situation surely they can’t be lifting heaving things into place as there is so little room.  This crane is huge and the arm stretches way across the road and beyond.
Today I looked up to see a man making his way along the arm. He wasn’t wearing any harness as far as I could see. This is Health and Safety Spanish style I think.
He inched along to the end

  lay down and fiddled with something mechanical and then inched his way back to safety

Yes, that small shape up there is him!
How was it possible to do this?  I couldn’t believe that everyone was just walking by normally while someone did an amazing thing way up in the sky.

He wasn’t wearing a helmet either – I suppose that if he had fallen a blow to the head would be the least of his problems.
